If you spend any time reading Bay Area home-buying threads, you've seen the same advice on repeat: grind it out for a few years, wait for the promotion, wait for the RSUs to double, save up that 20% down payment, then buy. Or the other camp: don't buy at all, just rent forever.

This post is the one I wish someone had handed me back when my income wasn't high and my savings account was basically empty. Because there's a category of housing you only qualify for while you haven't "made it" yet. The door is open right now. The moment your salary or your assets climb, it shuts behind you — and it doesn't reopen.

I'm talking about California's BMR / BMP programs — Below Market Rate homeownership. I'll break this into three parts: where these programs came from, why this is a compounding machine that's literally reserved for people who aren't rich yet, and how to actually get in.

Squeezing every last dollar out of your budget matters way less than catching the right window and using the right leverage.

Part 1: Where this benefit came from — half a century, New York to California

A lot of people hear "government housing" and picture public housing projects — old, run-down, out in the middle of nowhere. The U.S. actually took a different route: the government doesn't build the housing. It makes developers build it. And it's not a separate building full of subsidized units — it's a small slice carved out of a regular market-rate building, sold to whoever gets lucky.

I found out about this the first time when I was working in New York. I was living in Connecticut at the time, renting an apartment in a great location — walking distance to the train station, and the rent was reasonable. Turned out that building had exactly these kinds of units in it. The only reason a unit like that existed in a location that good is that the developer had signed onto the city's program.

So I went and dug into the history of affordable housing in the U.S. Here's the short version.

New York went first. New York and California have always been the most expensive, most supply-starved housing markets in the country — and this isn't new, it's been true for fifty-plus years. Everybody moves to the big city to make it, a huge share of them immigrants. Whether or not you got on the property ladder at the right moment ends up shaping the rest of your life, and sometimes your kids' lives too.

• 1950s — Mitchell-Lama. New York gave developers low-interest loans and tax breaks in exchange for selling or renting units to middle-income families at regulated prices.
• 1970s — the 421-a tax exemption. Build a new building, get decades of property tax relief; the price of admission is setting aside a share of units as affordable.
• 2016 — Mandatory Inclusionary Housing. New York stopped asking nicely. In designated areas, new construction must include a set percentage of below-market units.

California started earlier and pushed harder.

• Early 1970s — Palo Alto became one of the first cities in the entire country to adopt inclusionary zoning.
• 1979 — the State Density Bonus Law. Include affordable units in your project and you get extra density: more floors, more units to sell on the same parcel of land.
• Later state legislation (AB 1505 and others) locked in cities' authority to require affordable units in new development.

See the structure? It's a deliberately designed three-way win:

What this looks like in the Bay Area

Locally, this shows up as each city's BMP / BMR program. Take the City of Santa Clara (administered by the nonprofit Hello Housing): a portion of units in new developments are set aside and priced based on the buyer's household income.

Typical requirements:

San Francisco, San Mateo, Sunnyvale, Mountain View and others all run similar programs. The rules vary in the details but the shape is the same.

And these aren't tired old units in the middle of nowhere. Many are inside brand-new buildings — same lobby, same gym, same everything as the market-rate neighbors. The only difference is you might have paid half of what they paid.

Do the math on the entry cost: 3% down on a $550K unit is about $16,500。 Add closing costs and reserves and you're looking at roughly $40–50K in savings to realistically start shopping. That's it. That's the ticket.

Part 2: Why this is specifically a "not rich yet" benefit — the same window logic as a Roth IRA

I've written about this before with retirement accounts, and it's the exact same pattern. There's a whole category of American financial benefits that follow one rule: the lower your income, the wider the door stands open — and the moment your income rises, it locks behind you.

How many people hit $300K a year and only then realize: "wait, why didn't I fund a Roth when I was 25 and broke?" Back then your tax rate was low, and every dollar you put in would have compounded tax-free for forty years.

So the right mental frame isn't "I'm broke, I have no business thinking about buying."

It's: "My current income level just unlocked an asset that high earners can never buy."

Part 3: Let's actually run the numbers — renting vs. BMP buying, at 10 and 20 years

All figures below are illustrative examples. Rates, prices, and rents change constantly — if you want this run with your real numbers, come find me.

The assumptions

First glance: buying costs about $1,000 more per month. Renting wins, right? Keep reading.

Layer 1: Rent goes up. Your mortgage payment doesn't.

Your P&I is locked at $3,370 for thirty years. The only piece that moves is property tax, capped by Prop 13 at +2% a year. Somewhere around year 8–9, renting becomes more expensive month-to-month — and the gap widens every year after that.

Layer 2: Part of that mortgage payment is going to you

Of your $3,370 payment, about $480 in month one is principal — money moving from one pocket to another. That share grows every year. And if your income improves, you can throw extra at principal and accelerate the whole thing.

Twenty years of renting: roughly $1.15 million handed to a landlord. Assets left over: $0.

Layer 3: The Prop 13 bonus nobody mentions

California property taxes are based on your purchase price (rising max 2% a year). You bought at $550K, so that's your tax basis — forever.

Same building. Same hallway. And that gap stays locked in for decades.

Layer 4: Putting it all together at the 10-year mark

Layer 5: This works whether your life gets better or stays flat

• If rates drop: refinance, lower your payment.
• If your income never improves: your housing cost is locked while everyone else's rent keeps climbing.
• If your income takes off: pay it down aggressively, or pay it off. Meanwhile you no longer qualify — which means without this you'd be buying something equal or worse for far more money and a far bigger monthly payment.

The honest caveat

BMP/BMR resale prices are restricted. Appreciation is capped, usually tied to median income growth or a designated index. This is not an investment property and it will not produce market-rate gains.

What it does give you is three things you cannot buy on the open market:

1. An absurdly low entry point — a down payment in the $16K range
2. A locked-in cost of living for thirty years
3. Forced savings through principal paydown

Compared to "$1.15 million in rent over 20 years, ending with nothing," this isn't a hard call.

One more thing people miss

A BMP unit doesn't cap your future wealth, and it doesn't stop you from buying other property or making other investments later. You've solved your single biggest expense — housing — at a rock-bottom cost. The cash flow you free up goes into your 401k, index funds, whatever you want. The restriction is on the resale price of one condo, not on your life.

Part 4: The process — it's simple, but you have to prep early

Using Santa Clara BMP as the example:

Most people get stuck at step 3. They wait until they spot a unit they love, then start scrambling for documents — income verification, tax returns, bank statements — and miss the application window entirely.

The right move is to get pre-qualified in advance so that the moment a unit drops, you're already in the lottery pool.

And honestly, the bigger problem is that a lot of people are inside this window and have no idea the opportunity exists at all — especially first-generation immigrants like a lot of us, where English isn't your first language and nobody in your circle has done this before.

If you want help

I'm a licensed Mortgage Loan Officer (MLO).

If you're not sure whether your income falls under the qualification line, don't know how much you can borrow, or want to re-run that whole rent-vs-buy calculation above with your actual numbers — send me a message. I'll do a free assessment: pre-qualification review, figure out what price point you can genuinely afford, and get your income documentation package ready.

And if you don't end up using me for the loan, or you don't win the lottery this time — that's completely fine. Just going through the process means the next time you want to buy, or use mortgage leverage for anything, you'll actually know how it works. If I helped, I'm happy.

I got a lot of help from a lot of people on my own way here. I think relationships flow both ways, everyone's life keeps getting better, and once trust is built there are always chances to do things together down the road.

The window is open right now — it won't stay that way. Grab the ticket while you're still not rich.
