@Tim Porsche - disclaimer - I know nothing about Pennsylvania real estate law.That said, I don't see any recourse for you here on this issue, as they would likely argue that you had a chance to do your due diligence before writing the offer and/or could have written a due diligence period into the contract and chose not to.  

I had the exact same issue, literally about a year ago, but on my personal residence.

What sort of issues could I have by taking over the mortgage and renting the property out with the lender3.

No issues.

I didn't try Propwire when it first came out, by at 30 days they seemed to have fixed a lot of the initial issues.

Have some quotes going the DSCR route however fees and rates seem on the higher end, we have 790 credit score, good W2 jobs so documentation is not a problem and we don’t have an issue putting them in our personal names, but have had the MFRs for less than a year and operate out of MD.
