@Amanda SalvatoreYou would probably be better off looking to get a construction to permanent loan vs seller financing.

THE MAINTENANCE GUY IS RIGHT THERE, along with a permanent household of stuff, should the tenants need anything.

There ARE conventional loans for MANUFACTURED homes built after 1976 on permanent foundation but not for single wide mobile home still on the tracts (that's a car loan)  

What I don’t remember is how fast misplaced place people seek permanent homes.

If the victim suffers no physical pain or permanent deformity, the crime is a third-degree felony.

I  would  recommend  1) get pre approved  using whatever  scenario you want  2)  if  the  seasonal income  scenario isnt  approvable  -  obtain a  job that is more permanent   that a lender  will be able to  use for  qualifying you for a loan 

Accessory Dwelling Unit/in-law unit requirements)A: Current planning regulations prohibit any rental of a single-family home, duplex, apartment/condo, live/work unit, or room for less than thirty (30) days, based on the City’s definition of “Permanent Residential Activities”, which are defined as the occupancy of living accommodations on a thirty (30) days or longer basis, with none of the living units under the same ownership or management on the same lot being occupied on a shorter basis.If you are renting your single-family home, duplex, apartment/condo, live/work unit, or room for less than thirty (30) days, the Oakland Planning Code defines the activity as “Transient Habitation” (or essentially a hotel).

And why not, he gets fat fees for selling properties to pay off debts.She has to talk to her attorney, openly and honestly, if only to avoid criminal charges, but even still, the title company won't provide clear title on the transaction until the bankruptcy is closed or there is an approval by court order.

My goal is to buy and hold 10-15 properties to meet my regular/fat FI goals.

I want to purchase this home with the mobile home, but it sounds like if I want to finance it that is not possible.It sounds like the mobile has had it's wheels removed and has skirting around it, making it "permanent".
