Personally, I do not like any strategy or approach that aims to benefit from the misfortune of others.

If what you are aiming for is a BRRRR to acquire and rehab properties into cash-flowing rentals, you may with to try to feel less personally attached to the result. 5.

Aiming for larger properties on your first deal (100+ units) is definitely very ambitious. 

Those property use codes may come in handy for other purposes, such as when my municipality is aiming to ban STRs.  

Aiming to maximize cashflow to fund future investments, but as newly weds rent by the room doesn't feel practical right now. 

It's an estimated cash on cash return given current rental rates subtract expenses assuming 7% interest rate, 10% management fee, 5% repairs, 5% capex and other expenses like mortgage, insurance, tax. it's a estimate to tell you what properties to analyze vs ignoreyou can see the are pockets of negative returns as well as pockets of positive return. this is to supplement the data @Devin Conley provided

Newer construction code requires better earthquake-proofing, but it's still aimed at preventing a building collapse rather than holding the value of the structure.About 15 years ago there was all the talk about "100 year homes" but I haven't seen much come of that.

On the other hand, if you're aiming for long-term rental properties, getting prequalified with a lender specializing in traditional loans or DSCR (Debt Service Coverage Ratio) loans is key.

ETWhen Tylisha Slaughter learned that the West Philadelphia rowhouse she rented was going to be auctioned off in a sheriff’s sale, she sensed opportunity.Slaughter, now 30, aimed to buy the home near Cobbs Creek Park on the cheap and restore it from the “slumlord”-like conditions she, her boyfriend, and her two young children had been living in.But on the day of the sale, she said, she found herself up against an out-of-towner with lots of money to spend: Brandon “Dutch” Mendenhall.

If you want some cash flow, aim for secondary markets like Worcester or Fall River.
