For example, somebody makes a big burn mark on the butcher-block countertop.

I imagine that the ARV of a Tear-down would be EXACTLY the same as an equivalent vacant (serviced) block (based on comps).

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"??

If you get overly emotional about every decision, success or failure, you will drain yourself emotionally.

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?

@Jacob MallatAs far as a second kitchen in the basement, it is best to find a space below the kitchen upstairs simply because that is where you'll have a drain line you can tap into for the sink downstairs.
