So, the actual increase to market rent will be much lower.

Personally, I invest in properties in C-Class neighborhoods in my market (East Linden and Southern Hilltop), and they’ve been cash-flowing well so far.

on the one hand, if you're happy with it, and you believe in this market, and this is what you wanted, great. the fact that you're asking the question shows that you're being thoughtful about it.with that said, it sounds like you're into the deal for almost $90K out of pocket, and so if you asked me if i would put $90K of my hard earned cash into a property to get $175 month, the answer is no. 

Rental market is pretty strong, there are a lot of good economic drivers.

Housing is still affordable compared to other markets, which keeps renters and investors coming.

I use Facebook marketplace as my way of marketing my rentals.

The "best market" is less about the market per se and more about the deal you're able to find in my opinion.

I avoid the multi-family market here, so unfortunately, I will not be a good go-to here, but I am confident you will find quality resources and help here on BP.  

Hi Noy, Pittsburgh is a strong market for investors.

I know this is also a National issue, especially in land constricted markets.
