I wire-brushed the surface, painted again and adjusted the sprinklers.  

(insert some smiling small talk here) and then (lean in and softly) say - look; you know I have been meaning to talk to you anyway.

For simplicity's sake let's ignore the soft costs like closing, title, and inspection.Scenario 1: You spend your 50k on buying one of them outright, and your gross income is $9000/yr (750*12).

This thread is a bit old, however as the first responder suggested I've seen and heard many times the best suggestion is to use Kilz on the subfloor, of course replacing the bad soaked through sections.On Tile - I've personally used baking soda/water and a scrub brush - was time consuming and hard on the back, however rubbed the baking soda with a bit of water into the grout, let it sit for 2-3 days, then came back and cleaned the baking soda up with water and a final cleaning with another cleaning solution - good as new and no smell.Guess it would depend on the severity of the problem for the solution.

It's only those of us who are willing to get back up, brush ourselves off, reflect on our experiences, learn something from them, and most importantly - try, try again...that will be rewarded.Congratulations on your courage and accomplishments! 

I'm a lazy buyer in the soft markets. 

Do a bead on the back and spread it out to cover the entire back surface with a chip brush.

This is not a bad thing as long as it is a healthy correction and soft landing.  

I recently had a contractor come out to a property in Whittier, CA (1640 sq ft home on a 6400 sq ft lot) that needs a complete gut rehab and below is the soft quote he gave me and everything he'll cover for $170K. 

I've always been interested in tiny house living, or eventually buying an RV to travel, so living in about 1,100 square feet under this house hacking scenario would be a soft step towards towards that.
