I am in the Chicago area and am looking at a house with an indoor pool.

painted in doors, added new garage door, fixed some interior doors and trim. new oven.

Prostitution ,Bars in doors and windows  No nice houses many blighted .very few newer cars .

The indoor area of the house is about 5300 sqft not including the size of the double indoor garage.

*never use exterior paint or primer indoors because it for off-gasses for months**Mud the wallpaper seams with Joint Compound, mud pan, and tape knife. 

We just closed on a loan for a client, and during the process everything that could go wrong went wrong.First thing we found a hidden indoor swimming pool that was covered by a wood platform in a very large rec room.Then come to find out a little kid drowned in the pool, the local insurance agent comes out to take pictures of the house and he said he wouldn't enter the house because its haunted. 

.- A/C contractor has already replaced the main house indoor and outdoor unit, he is going to replace the garage apartment units Monday, then all a/c work will be complete.Good News:- Savings of $1,850 on AC units vs. our budget!
