When I first got started buying rentals, I did some research and stumbled onto the “1% Rule”. Basically it says you should collect every month at least 1% of the house price. So for example, if you pay $1M for a house, you should rent it for at least 10K a month.
I was looking for rentals in the North Bay at the time and I told my agent about this rule. He was polite but basically said “You are out of your mind”. It was 2011 and even then it was hard to find properties with the 1% Rule. If you go on sites like Biggerpocket many people still talk about the 1% Rule, but you can only find such deals in flyover states like Kansas.
So what’s the rule of thumb for us in major league areas like the Bay Area? I calculated for cash-flow neutral we can use the “0.5% Rule”. Let’s work out an example. I use 1M because it’s a nice round number. Math is the same regardless of price.
Purchase Price: $1,000,000
Down Payment 25%: $250,000
Financed Portion 75%: $750,000
For mortgage payment every month, use my rule of thumb: $500 per $100K financed. So mortgage payment = $750K / 100K * 500 = $3,750
Property tax is 1.2% per year, that’s 0.1% per month: $1,000
So the “PIT” part of PITI is $3,750 + 1,000 = $4,750. Now put in $250 per month for insurance and other expenses and it comes out to $5,000.
There you go: $5K = 0.5% x $1M.
Even there your cash flow will likely to be slightly negative because we didn’t account for repairs and vacancies. Also property taxes will most likely cost you more than 1.2% with all the parcel taxes. It’s a “rule of thumb”, not a detailed Excel model. But I like to buy houses on the edge of cashflow neutral anyway. That’s a good way to play offense while still have some degree of defense.
