Priceton,You are correct. 

If your policy has an 80% co-insurance clause it means that you must maintain a limit equal to or great than 80% of the actual cash value. 

If you purchased the property correctly, the tenant's rent payment will cover the mortgage.

Am I crazy, my only out of pocket expense is what it costs me to maintain that debt?

It sure sounds like you can 1031 exchange in to property in one of these zones and if you hold it for 10 years all your capital gains with become tax free. 1) is that a correct representation of what it is?

I changed properties to a much nicer neighborhood (A-) - right behind a kids religious school/church, state maintained park, and all houses on in the vicinity are well-kept and sell for 105k+It definitely was not worth investing in a C neighborhood with my significant other.  

Why in the world is costar allowed to maintain the monopoly on listings they have for instance?

A personal home is a life style choice not a investment.Due to the fact that a personal home is more expensive to own and maintain renting while saving to invest is a smarter option for those wishing to concentrate on investing.

A $1k rehab won't demand more rent, and maintains the status quo. 

So if I am understanding this correctly I will either get some if not all of it back when I file my 2018 taxes correct?
