The harder part is managing a rehab from afar.

Investment Info:Small multi-family (2-4 units) buy & hold investment.

I am going to document costs and upload videos showing the construction process. 

•If you purchase a multi-unit property next, rental income from additional units will help you qualify for a larger loan.Final Thoughts•If similar homes are sitting vacant for months, it may not be the right time to convert to a rental.

(the messaging/CRM platform, not the 1980's video game)I'm curious to hear of any recently experiences with it.... is it worth the high cost of entry?

Working this backwards, what I see is a 3rd party trying to benefit from another’s house via rental cashflow, My only business is 30+ years as probate estate and trust lending in CA.

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).

I would suggest reaching out to owners of multi family who have no loan on the property.

@Caleb Genry I am late to the party on this, but would greatly appreciate the spreadsheet/log if you are willing to provide it. 

For CRE I want too get into the Multi-family niche that's what I have interest in. thank you for the advice
