Some thoughts are - the neighborhood or block may be high crime / poverty even if the overall area is considered nicer (like a D block in a B area), the property is overpriced and the seller won't budge / low motivation, liens on the property (I'm not really familiar with tax and title and legal stuff but maybe something like that?)

The property management company tries to bring people through during blocks of time (like 4:30 - 6:30).

They say its because there's no "DSCR" block (true) but why not mark it as "other"??

Some times it's just nerves or mental blocks, but keep at it.  

there's a few house appraising software out there that could show you the appreciation block per block.

Knows what block is better and why.A good egg.Sells real estate as their sole income and passion.Has a network of handymen, contractors, insurance, CPA's, legal... who do they know that can help me?

We have a lovely home about 3 blocks back from the beach in Port Aranas Texas.

I’ve seen some examples where same house a block away (one zoned for rental and the other not) being priced 50 percent apart and the one double in price (zoned for rental) selling much faster than the other. 

The plumber stated that there were roots and about 6ft of "flushable" wipes that were blocking the pipes.

In addition, the electrical box is in the middle of the finished space with nothing blocking it off.
