Upon closing I put water pressure regulators on the main lines in- we have pretty high pressure, municipal water- this will give those old pipes a break.As for the neighboring buildings- I have renovated all my units before I have put them for rent.

You should not feel pressured or guilty about it, this is totally business as usual.  

I believe SFH will feel some pressure but not MF, unless it is self inflicted. 

If you really feel the need to do "something", I'd start with pressure washing everything, then paint the trim and siding to whatever contemporary colors are hot in your area.

Proper siding generally withstands pressure washing, which hits it with heavy PSI and at the opposite angle of what is normal (from the bottom). 

Inside I run some water to make sure there's pressure.

@Tom Gimer Okay, I see....get the lender scared and they put pressure on their policy title insurer.  

It cuts the flow of water and saves waterAdjust the water pressure on the main water line coming in the property.

Thats put a lot of upward pressure on prices and i expect it will continue to do so.

I found that , yes, I saved on taxes, but that maybe without the time pressure of those 45 days, I could have sat back and maybe found an awesome deal (instead of just a good one) , that would have ultimately created more profit for me than what I have saved on taxes.
