I own 4 two/three flats bought between 2013 and 2020 in Forest Park, Illinois, at low interest rates and prices in 200000's  They cash flow nicely and prices have increased a lot. 

In beach markets, in ground pools tend to increase revenue 20% or so. 

The shorter the prepayment term has an impact on increasing the rate.4.

House hacking is a financial no-brainer, it eliminates you single biggest monthly expense, so you can increase your savings rate.

So if prop 33 passes it will be possible to cap rent increases from one tenant to the next.A recipe for blight.  

I increased my Heloc on my primary.

the key to a BRRRR, whether it's going to be an STR or LTR, is this:distress.you need to find a significantly distressed property, such that you can increase the ARV via the rehab. 

This will increase the return above what can be obtained on a passive investment.The flipside of having the power to control everything is that it can be alot of work (and a full-time job if a person is putting in sweat equity).

So the added cashflow to property owners it they are willing to become the developer and increase density that tactic could help more owners stay than could otherwise afford to stay. 

At annual rent increases, I do scour Zillow for market rents in the area, which I share with my tenants.
