@Steve Vaughan is awesome in Wash State.

I swore up and down I wouldn't do what so and so did but then caved under pressure.

When I took over I put a pressure regulator in each building, this brought costs down and will likely prolong the life of the pipes.

Outside faucets turn off inside the building, no car washing or use for gardens.. 

Additionally, the contractors power washed the stone facade and noted that it was "holding in a lot of water" and needed to be sealed.  

Bernard,Wow... where do we start...Right off the bat, you need to figure out what the mortgage payment will be... so...280K (purchase) -12K (Taxes)-97K (first mortgage)-16K (Commercial mortgage) =155K (new mortgage)155K @4% for 30 years is $740/mo$740(new)+ $810 (first) + $110 (commercial) =  $1660/mo1% rule = 280,000 x .01 = $2800 so call it a wash at $2775 income (Pass)50% rule 2775*.50 = 1387.50 but your payments are $1660/mo (Fail)My further analysis indicates a loss of $150/mo using the following:10% Capex, 10% reserves, 10% management fee, $2200 insurance, $3000 taxes, and 0 in current expenses, all of which which is pretty generous.

If there's water, someone washed it recently. 

LolNow, with ex paid off the loan this time, I don't even know there IS a new mortgage taken out...What ex told me was he took a HELOC from his primary and paid off the loan on the rental... 

If the odor is actually powerful, you need to throw out the old carpet and wash the cement under it with powerful soaps and acids several times
