Darren,This topic has been gone into exhaustively fairly recently.

The "surplus" generated is paid to junior lien holder claimants in a pro-tanto order, if any, until secured junior claimants are exhausted. 

I would not use a skiptrace unless you have EXHAUSTED your resources.

It's an exhausting, and years-long effort (or at least it was in my case), and you will STILL be disappointed at the end of the day by the failure to take action on the part of some of those you volunteer on behalf of.

In my case, since I'm a pretty new buy and hold investor, I've often been advised to continue to acquire properties on my own and exhaust all of my capital/financing resources first before taking on a partner.

Yes you can run an aluminum (chimney) liner down the chimney (assuming it fits & there is no blockages) & hook the hot water tank exhausts to it.

I do not abdicate having smokers in units however for some landlords it might not be an option.If he has exhausted funds from using a contractor who did not clean properly then it might costs thousands to fix the problem and another months lost rent which the landlord might not have.If that's the case placing another smoker tenant might make sense.

Most of my cash is exhausted and I have just some left.

Some like to do their own exhaustive comps, which we review, and others have so much experience in their areas they can estimate sales prices better than anyone by holding their thumb up.

We mainly worked in Dupont, pharma and process facilities including clean rooms and I welded a lot of stainless lab hoods and exhaust.
