Remember you can only get a contract from a MOTIVATED SELLER.

This has been very helpful and motivational!

What is the owner's motivation for selling?

So I am assuming these properties are not in distress (foreclosure, REO, short sale), so what would be the motivation of selling a property in the web site (or what would be a buyer's motivation to buy such a property instead of just buying a non-auction property which can be inspected)?

I'm new to buying wholesale properties but I would think it would be easier to buy wholesale properties from motivated sellers in a pre-foreclosure or handy man special than a bank owned property? 

I got a lot of people saying that they were interested but no follow it terms of preliminary contact information :/ So at this point the buy and hold folks will remain in dormancy.

The remaining 19 will be renovated and rented.  

a year or so ago, there were line ups around the block to buy a pre sale and now we have units that are almost complete without a purchaser in place for some remaining units. 

In PA, the quoted excerpt would be wrong and bad advice to follow, since the tax sale is conducted "subject to existing liens of record" - so the mortgage would remain in place, and the buyer at PA Tax Claim Bureau sale would end up having to pay to get clear title.
