We typically use Kilz on all the floors to mask the smell as well before putting anything new down (assuming you are going to carpet or put planks down).  

As I was masking off the floors to start painting, I got hit in the face with with overwhelming ammonia smell from that corner.

@Cheza M. when choosing a PM company you will want to review the PM agreement with a fine tooth comb.

Maybe we will build and sell and we do a 1031 exchange into 2 properties in the Midwest or we hold onto too the house for a couple of years and let it appreciate more.

It hasn't change our policies though, other than offering to make sure everyone has masks and gloves on before entering.

Either way a sawzall type saw with a 14-18 tooth blade should make short work of it.

I told her that was OK with me, that I would mask and glove up, and was willing to risk it. 

Once they start, they build up their own constituents and beneficiaries (and employees) who will fight tooth and nail for continuance, and there has never been a politician with the strength of character to say "No".And who can really blame the politicians?

That can be said for investment properties and handing those off to PMs too.

However, you may try to go through their information with a fine-tooth come when you get down to the last few that you think you will be renting to.
