If you answer the phone and there is an uncomfortably long pause before someone talks, it's a machine dialed number and simply hang up and block the number.

Im not advocating for this, but simply stating that it is the norm for whatever reason.

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).

So when my clients work with me, I simply guide them through the process of originating their own loan (legally, in the states that allow it).

You simply disclose your license to the Buyer and then use the correct documents and verbiage, you're fine. 

I am not a tax professional trying to sell you my services I am simply providing my perspective. 

If I am reading correctly, they are simply supplying the money for the partnership. 

When the numbers were tallied, he had actually lost about $10,000–$20,000 per property.Here’s the kicker: Had he simply bought the properties for $80,000, left them vacant for seven years, and only paid taxes and insurance (about $1,500 per year per property), his all-in cost would’ve been around $90,500.

Over the years, however, we’ve found that we end up coming down to Orlando quite a lot, especially in the last couple of years, and we end up staying in vacation rentals (Reunion, Championsgate, Storey Lake typically).I would love to simply pull equity from the current property but given that it’s a long term rental and we are Canadians, from what we understand it’s not an option for us.we love reunion but I feel that would probably not be the best for ROI.
