A lot of things can go wrong and there is more moving parts.

@Chris Seveney I for some reason recall when I lived up north in some locations heat went out and if it was longer than a specific peroid of time it would deem the unit uninhabitable - but I absolutely have been wrong in the past.

Am I doing something wrong in my underwriting methodology? 

Plus by going with you, they won't have the benefit of an agent's errors and omissions insurance, the support of their brokerage, and the experience an agent has in protecting their clients from everything that can go wrong in real estate transactions.

And the fact that your post had at least three votes for it when I posted this shows that there are lots of other people who would probably be losing in PA under those same assumptions that just happen to be FALSE in Pennsylvania.Pennsylvania has some rather complicated rules when it comes to tax sales; the particular type of sale that the OP purchased at is one that does not divest any liens; it simply changes the party that is the owner, with the new owner taking title subject to all liens and encumbrances of record.With tax sales, the buyer must be aware of all the local rules under which the tax sale is being conducted, because the rules vary all over the place.Now, what the OP seems to have failed to do in his research was to cross index the recordings at the county recorder; the "missed" mortgage would have showed up on a search by parcel number if that sort of cross check was done (and assuming all indexed documents at the recorder are properly indexed of course - I have seen mistakes made attaching a document to the wrong parcel).

You're in the right place, you just have the wrong attorney and agent.

But your can't go wrong with either.

If you think that bad guests are only on one platform, you are dead wrong and that’s the truth.Enter in the evictions.

There are a few concerns that made me question going through with it, but I have a few contingencies for backup if anything goes wrong.
