You don't know cold until you have your nose hair freeze after being outside for 30 seconds.  

If it is several rooms and they need washing I usually get a helper to wash and clean while I paint and to remove tape before paint dries, clean up paper or plastic etc. 

Down the sanitary sewer is a better option than the storm sewer since who knows whats in it.Then get a big shop vac and go to work to get what's left.Then get dehumidifiers and run them until its really dry.  

Keep your powder dry and just put in what's required.

Do the next owners a favor and do not put down the carpet, they may want the hardwood if not it is easy for them to install the carpet.Our floors are in no way perfect but neither are the apartments so they complement each other well (some people pay extra for the “distressed look”).Total cost for me was ~ $300 (sander rental, sanding pads, poly) and took a solid weekend myself (plus a day of drying before the second coat of poly).

But then I found this guy named Mark Whitten in Baltimore he had a book " How to flip houses like your hair is on fire" So i googled testimonials actually emailed him and found him out to be real and not a gimmick.

So here's another tidbit I've learned:  always have a "get out of town with your hair on fire" exit strategy to go with the standard multiple exits. 

Runs short on his own flips and they sit dry losing a size spread of profit.  

I thought HMLs in my market were are all but dried up, but I was able to find one on BP no more than 6 months after I joined.

They have 3 big dogs and 3 cats; however, I am getting $100 bucks a month more out of them then what the area calls for and they seem like "good people", so if the dogs chew some horse hair plaster or the cats pee in the corner, it's not a great lose..
