Transparency is always the best approach but generally its been my experience that there are very few wholesalers that act in transparent ways to the sellers and buyers and try to keep everyone as much in the dark as they can.  

Dang you got my attention.We had a 10 year old kid running around in the dark and fell in an area that was about 3 feet down where the entrance to the basement is on the end of the house.

Theodore - I don't recognize the color, but I would send the photo to a couple of "big box" stores and see what they suggest.

So if you look at the map and use the umbrella zoning color codes to know at a glance if something is residential, commercial, etc and then begin to zoom in, then you'll eventually be able to view specifics like R-1, R-2, CEIR, etc. 

Especially the dark roast.

Hard Money Loan - I do have a nest egg (40K) to put skin in the game along with the majority of it coming from the HML.

like mentioned above CLEAN  windows seals  PAINT  cracked ( gator skin ) looking old paint    .only one house we replaced all the windows  as they where dated   just make sure you know what the inspector needs and is looking for and you will be fine and the tenets will be safe :)

I would bank on 25-30% of build cost as your skin in the game.

A down payment is skin in the game.

Its been a true blessing to have gone to the weeds of it and grow thicker skin!
