There may be a mortgage on the land or a loan secured by the mobile only, or a mortgage on both if the mobile has a permanent foundation.If it's under contract, why can't your "seller" provide you this info?

Not working more hours than that (750) for any other income.Then I realized that when managing multiple properties there are additional rules and to get around it one can permanently elect to treat them as one but then it could fire back when selling one of the properties... and then I am lost.Can you recommend prescriptive guidance on it?

In CA my larger expense it the Fat *ss mortgage that is MONEY IN THE BANK for me. 

"Green card" holders (although they're not officially called that anymore) are permanent residents.  

If they decide after 18 months they dont want to flex their option to buy, its even better for you because you keep every penny they spent on the house, and then you can start over and collect another fat payment up front with another 18 month lease option.

In fact, the manufactured home's existing supports are still necessary for the load displacement, reduction of floor vibration and for leveling adjust-ability.A retrofit is generally required to meet loan or insurance specifications for "permanent" attachment, wind resistance, snow loads or seismic resistance.

Should I push the other owners to either start the HOA, or permanantly remove it?

Once you get the first deal under your belt continue going and don't get lazy after the first deal some people will after they get that fat check of $2,000 or $15,000 check.

Good enough equity, trust, and a nice fat n juicy interest rate?

But my wife is the one who makes more but she is currently on a temp status which may or may not go permanent.
