. ⭐......such as Education, Race, Crime, Poor & Corrupt Political Arena......For instance in on Cleveland's Lower Westside you'll see Gentrification even if hit & miss while on Cleveland s Lower Eastside you don't & won't for awhile & the contributing factor is poverty, to degree race relations & emphatically crime.

A big factor is whether they are split (3 bills for 3 homes) or common (1 bill for all homes)- Security deposit: one month rent is common, due at lease signing- Is there a way to add value to some/both/all homes - add washer/dryer, dishwasher - to boost rent potential?

The most important factor is buying it at the right price that leaves you enough room to make a profit after fixing it up. 

I actively avoid HDLC controlled area, due to the excesses cost and lack of exterior design options, but if the pricing is right for the PITA factor, I do consider projects. 

Big Timber left Portland long ago moved their head quarters down south.. think LP Boeing has been moving out of WA for years  think Chicago and new factory in South Carolina.the deep south saw huge influx of car manufacturing even the lowly state of Mississippi got the big Nissan plant 25 years ago..

Really I just think about the classic tale of the small declining town, which has been headed downward since the factory closed down.

The "Boogie Nights" Hollywood-adjacent factory for porn movies was run off by condom regs and online X-cess.

I am assuming she is still paying but if she is a PIA the plan to either terminate or raise rent to compensate for the aggravation factor is a good one.

@Russell Gronsky#1 it's January, so you're still chasing last years market, come back in a month and you might fare better#2 sometimes an over-improved unit in a less desirable neighborhood will have a harder time finding a buyer#3 the train tracks are a factor, I recently closed on a two flat next to the highway, it sold at a 10% discount to similar properties a few blocks away

New homes in most markets cost around $40,000 to $60,000 including shipping and set up if you can buy factory direct.1990's used homes (mostly repos) cost around half that.1980s homes cost around $15,000 set up and renovated (but are very hard to find in salvageable condition).You can find the new homes/factory direct at CAVCO or Clayton (if you are a park owner only). 1990s repo homes come from repo lists from 21st Mortgage, Vanderbilt Mortgage, etc.
