So you can hold it as a rental for close to 3 years and still take the exclusion, as long as you sell it (and close on it) prior to the 3-year anniversary of the conversion.

Perhaps leave unit B until their anniversary date comes up and then do a modest $10-15.  

August 12, 2014 will mark my 4 year investing anniversary :-)I wish I had started earlier, but honestly, I think I was very fortunate to start at the perfect time and to be in the right place at the right time.When I got into RE, I went all in and pursued it very aggressively.

If you leave a sill, get one that is waterproof because that is where they will stack all their soap and wet washcloths. 

It was cleaned using Murphy's oil soap, causing a film on it.

My 10 yr anniversary is tomorrow with my current company and my reward is a world band radio!

Oh, one little tip if you do decide to re-tile a surround: in rentals, I do not install a soap dish on the long wall...instead I install on the wet wall (where the faucet is).

They just celebrated their 5th anniversary.

One of the statements was "instead of paying off their mortgage on the 30th anniversary of when the bought their house, they will have to move out."

Soap box removed.I run my own crew, am my own management, and so I dodge much of the BS associated with having others manage my wealth.I have been doing a small side business setting up Sect 8 rentals for out-of-town investors...its all individual and negotiable.
