A duplex should have a lower cost foundation and typically has less windows and exterior.

We would like to split the homes and both have separate LLC’s moving forward.

from what i know it usually takes about 6 weeks for the entire process, if you file for eviction you can usually get the home back, these situations are hard, more often then not the homeowner doesnt know their homes were ever put into auction and lose their homes, but usually with talking to the previous homeowner and proving you are the rightful owner you can get the home back, or at least negotiate them to leave cash for keys , if that doesnt work then file for eviction or notice to quit. 

Several newer homes and growing area.

In 2019 there were 10,000 homes for sale in the Poconos.

Now, wholesalers will say that they are not selling homes, but are selling contracts and this is kind of a gray area. 

Those who are most successful buying SFH's buy in markets that experience a sudden  appreciation event/spike in home ownership  creating an end buyer market that no longer consists primarily of investors.

Inflated ARV's and underestimated rehab costs are common practice with most wholesalers, much of which are newbies who have never flipped a home themselves.As another stated, there are other ways to land deals besides wholesalers so cast a wide net and use multiple avenues to funnel your leads.

If not I would pass and rent it as is (if in good rentable condition.)I only go into a full rehab when I am ready to sell the home. 

In France (my home market), money goes to a segregated account.
