The work around was a Mexican bank was the owner and lease it to the foreigner.

@Zach Denny  Similar to what Minna posted above, I have done with a local portfolio lender bank where they set their own lending rules. 

I recently came across 1 acre asking for 314k in a very good residential and growing location, so the current owner has added 4 manufactured homes with 4 electrical meters, 4 septic tanks and only 1 water meter for all 4 homes, the homes are sitting on partial slab and partial pier & beam, he also added 2 storage sheds approx. 380sqft with the intention to make them ADUs they are still only the shell so I would have to get those ready to live in, so currently the 4 manufactured homes are being rented and bringing in 2800k a month, 3 of the homes are needing some TLC which could increment rents and possibly get me at 3600k a month, also being a 1ac lot this still leaves about 12,000sqft of raw land where you could build etc.So that is on the good side now the things I did not like so much, the lay out is poorly executed to where it makes it looked crammed up and not professional but it could be fixed.Another is that in reality there is only 4 livable units so that qualifies under a conventional loan but since they're are 6 units on the property the banks are wanting to take it as a commercial so we would have to move out the 2 storage sheds out in order to close as conventional.Another concern, technically you are only allowed to have one manufactured house or single wide in your property according to what I know but I know it could change according to zoning which I will investigate, so my question is has all this been accounted for and if so how can I verify it so it wont leave me in a bind further down the road, I currently asked my agent for the appraisal of the property to see if that might verify.Any recommendations?

There are also additional costs of operating and maintaining an LLC, like separate bank accounts, annual report filings, tax filings, etc.2.

Go to small local/regional banks NOT national ones.

Retirement accounts are designed to be invested passively so when the IRS sees you running an active business in it, to level the playing field between retirement accounts and other business the retirement account incurs UBIT. 

@Michael Klinger  As others posted, SoFi and Discover personal loans are good options and I've used them in the past.  2-3 business days from application to funds in my checking account. 

We're in a small town so we ask our bank loan officer who is involved in the community for a CPA reference.

How to avoid BEFORE this happens: pay a day early, don't raise issues, get loans that aren't backed by US Government that the note states they don't sell the servicing.How to avoid the late payment- pay all accounts from the same bank account on the same day of the month.

Hi,I suggest you create a bank account with one of the bigger banks in your area that has many locations.
