You will have a lot of trouble with them, find a good mason that works fast, I say mason because any wood, metal or plastic fence will be destroyed over night, build a block wall and fill it solid with concrete and rebar.

You don't want H&R Block. 

When ~1/4 of the block had been noticeably improved, you’re probably safe to get in.

Hi Ricardo Welcome to  Connecticut MarketBidgeport is a good market depending the area like any market you can be in a nice are and 2 more  blocks down you'll be in a war zone but the best part is that bridgeport has the most affordable market compare with the others cities closed to NYC like norwalk not even talk about Stamford here the taxes are little high but  the income compensate that be careful with Real Estate Agent that says they are Investor Friendly and they just want you to buy at high price so they get a good commission but over all bridgeport is a big city trying to get betterbest area is black rock but is expensive, Hallow are is good for cash flow but a lot of the area is hot zone, east side war zone but could be some ok section, north end on the border of Trumbull nice are, east end like Stafford ave and Connecticut ave this are in this days is war zone. all of this areas and what I said about them are my point of view so you can see what others investor says about it wish you the best on your investment and see you on the top :-)

The house is on one of the worst Streets in the town, but it is several blocks from where the problems are.

Is center mid-block or at a hard-corner of signalized intersection?

Hello,Over the last few years, I have inadvertently stumbled into DC rental real estate investing, and now I’m hoping the more knowledgeable folks here can give me some ideas on how to proceed.In July of 2013, I bought a 2 bed / 2 bath condo a couple of blocks south of Petworth metro.

It looks like you have enough room unless there is a toilet blocking it. 

Or the Block Industries case from the Summer of 2017 where the Tax Court unraveled a “Magical Options Contracts Make Roth IRA Instantly Huge” scheme.
