So don't leave anything in an MTR that is irreplaceable.In addition to security deposits, you can also use the AirCover program for Airbnb bookings and third party services like Waivo and Safely that provide mini insurance per booking.

What are some of the best techniques to shut down those who protest against landlords who want to charge high rates in a neighborhood facing gentrification?

I have about 10 doors (started with 2 a couple months ago), I have been trying the farm technique with Realestate brokers in my areas but I want another route.

About 20% use DSCR (usually 20-25% down) and the rest are cash or hard money or something else.For $325k purchase:1) As a broker I would negotiate down as its been on the market a while and its especially now in holidays)2) I would also negotiate seller paid closing cost credits, most loans allow 3% which should cover most or all of that.3) Assuming you paid $325k but got closing costs covered I would anticipate a minimum of $32,500 down and maximum $65,000 down depending on lending product chosen.4) Remember you still must furnish and I use $20/ft as a safe estimate to fully outfit an STR property.Best of luck!

There are often long stretches of flat SFR markets in US. like '79-'83, '89-'94, or even down markets like '06-'13 where single family home values dropped 36% on average across country, so 1% rule may help keep some investors out of trouble by at least having some cash flow to safely carry the mortgage during those times.      

However, it’s important to ensure the area is safe. in those areas I would recommend checking local crime statistics on SpotCrime. you can use this link for an example,to get detailed information: https://spotcrime.com/map?

Even if someone gives you the lay of the land, you would still want to go there to see for yourself, just as you would definitely have someone come check out Dorchester to see what they consider safe and not safe.

Repairs would generally be for costs <$2,500 using the de minimis safe harbor. 

I think it's safe to assume that all investors' capital is gone here.

Usually FSBO listings (but there are other techniques).
