Each block of weeks rent for different amounts.

A smaller house on the same block sold for $106k, other sales range between $65k-$85k. 

I went to brelion.com and signed up however they block access until they verify accreditation status and claim it could take up to 21 days.

Talking about the 80's makes me think you've been around the block, but where is your BS Meter?

I've read that lenders won't include STR income, therefore I could be blocking myself out.6.  

Granted I know you are not hitting specific target homes but what if your piece went to every home on multiple blocks in target area and it hits some target homes but also hits homes that open channels to target homes.

Every block is different and some are definitely dicey, but there are some inexpensive properties that can be turned around and offer some appreciation potential.

If the vacancy rate is higher than 15/20%, it means it's one of those boarded up blocks, and thus I tend to look the other way.

As of yet it hasn't been an issue other than blocking my getting into the garage with my car. 

We do, and so far they are all within a few blocks of each other, makes things a lot easier!
