I really will have to come up with a creative solution if I cant remove the stain as the rest of the house is a few days from completion and the shower surround tile/glass door etc are already in place.

You can install a lockset with deadbolt in there in like 15 minutes.

You may be able to reduce costs by installing a roofing system over top of the existing system. 

I would coat the walls, floors and then maybe carpet or tile on top.

I know this answer could be a HUGE range depending on the upgrades we install on the interior but any information would be very helpful.  

If you were doing hardwood I would do it throughout, because that will bring much value.I did a lot of research on luxury vinyl tile and it really doesn't increase property value.

I found out that tile work is enjoyable for me, I also found out fixing mistakes is an awesome feeling.So at the end of the day if you can live in a property and fix it up there are ways to make it work and turn a profit but if you make a mistake along the way no money in world can pay for the knowledge you will acquire fixing your mistakes.Also in addition to my experience I am happy I did it this way because there was far less pressure on me to get things done.

DJ,In any investment scenario, whether for buy and hold or flip, we always put in a drain tile system with a battery backup.  

After some negotiating, he has offered a non-exclusive agreement, with 5% commission for the aggregate of the lease term (20-25 years), due within 3 installments, first upon bank receiving all final approvals to build, 2nd when the bank starts paying me, and third at the end of the first year of lease.

Anyone in the Seattle area know of a good handy man to do some hardwood floor installation?
