When I worked with a property management company, we had someone buy a unit (single family) that had a STR and marketed it as a STR.

Charge market rent. 

Here’s our OPINION for the Metro Detroit market (use as a template for your target area!)

Currently you have a STR lease and can effectively move anywhere the job market takes you.

At the time, we were new to the market and, admittedly, didn’t conduct thorough due diligence before buying.We purchased a property in the Atlanta area, renovated it, and listed it for sale.

To be clear my goal isn't to have a bunch of cash flow Y1 but just looking to break even.2) How could I go about finding markets where MHP are more beginning investor friendly?

There's a tenant that's month to month, rent is at least $800 below market rent, so I told the seller I need that unit to be vacant.

New builds-broke even in the '08 market on two spec homes, built my own home from the ground up twelve years ago(400k in equity). 

I’m giving serious consideration to converting into a PadSplit.However, I have heard that Fort Worth (the city, Tarrant County, the faceless boogey man…) has issues with PadSplit whereas Dallas County is supportive.I would love to hear about your experiences between the two markets and if Fort Worth can be viable for PadSplit and anything I should be mindful of?

Being thoroughly familiar with the local market is key.
