Home went to tax sale county kept excess proceeds.

You have three choices...transfer the property and keep the loan in tact hoping they won't trigger due on sale, refinance into a loan that allows it, or simply leave things as they are. 

when you say "being sold" do you mean the minimum bid amount or the actual sales amount? 

How about a sales contract with contingencies but with a limit where the buyer can only terminate the contract if their find material defects exceeding a certain dollar amount.

The "due on sale" clause is a non-issue here. 

There are a couple of car washes in my local area that are for sale that I am interested in but do not know where to start. 

Purchase price: $123,000 Cash invested: $50,000 Sale price: $210,000 House was empty for 2 years before we took over, is was in deplorable conditions but in a C/B- area.

So if I understand this correctly, by qualifying to extend the 5 year rule to 10 yrs, $250k if single or $500k if married of proceeds from this sale would be exempt from capital gains? 

Cash invested: $60 Sale price: $365,000 Sub-to deal with homeowner pre-foreclosure How did you find this deal and how did you negotiate it?

Most purposes that people on the BP forums are transferring properties to an LLC, would be exempt of the Due On Sale Clause.
