Your Heloc rates should fall for the next year or two. 

when you buy at tax sale don't all the mortgages and liens except IRS automatically fall off ?

Quote from @Davin Manfredi: This is a construction material on the remodel or work done on the home, so I would say it would fall on you.

So if you have a lawsuit for a fall through a deck board or whatever, they can only go after the one asset and not all of them.

Eventually, you'll find a problem that is not that difficult to solve (but kept other buyers away or forced the property to fall out of contract a time or two).You also have to know what a deal looks like.

However, you would have to rework your current contract to be subject to SS approval  (which the buyer may or may not be into),or sell to another party, and if you are getting financing for the new house, that will likely fall apart as well. 

If the appraisal falls short, I risk losing the deal and my $1,600 upfront cost.Any advice on navigating this would be much appreciated.

Or did these kind of fall into your lap? 

I apologize for anyone who falls into this category but I need to discuss this because it's a pet peeve that bothers me so much!

I just closed on a duplex in Dayton for $189K $1100 a door and have an investor closing on a 4 unit for $325K in Indy with great rents that cash flow over $1000 a month.I have seen Indiana, & Ohio pick up some major heat over the last 3 years for investors while Boise falls somewhat short.
