Like any city, there is dilapidated housing stock in rough areas that can cost more to upgrade than they are worth. 

Houses have gotten bigger. 2.   

I currently have a 4/2 SFH/LTR/Section 8 house under contract and I am getting quotes for property insurance.

Lots of older houses but there seem to be several that have the potential for cash flow and while not exactly modern on the outside, have been renovated inside. 

Rents have been pretty close to what the housing authorities advertise, sometimes even a bit higher.Fort Wayne’s a solid spot with low taxes and good cash flow—definitely worth looking into.

It seems to me that they all whether paid of free, will all have the same exact amount of houses because all the transactions are all public and so they seem to compete with each other based on the quality of the data of the houses, how up to date it is, and the user experience in configuring the how the layout is.

You can get houses at huge discounts and it is a great time to buy for appreciation.

A "lake house" might be in a residential zoned area where a commercial use would be prohibited or at least require a variance (approval) to make an exception.

May allow you to get more rent vs the same house next door without a pool. 

If you can get a big 4-5 BR house with a view for a under a million bucks, i'm pretty confident you can cash flow it with a good return, even in a 6%-7% interest rate environment.
