However, I am unfamiliar with any lenders having traditional mortgage options for anything with a VIN number such as a trailer.

If you don't want to put a single dollar down then you can just structure a 100% financing with the sellerHey Ko, it’s nice see you again.I’ve spoken with the seller and they want a 10% down.I think I’m going to wholesale this deal if I can get good terms, but every once in a while I come across a good deal that I would like to purchase as a buy and hold.what type of loans would you recommend for traditional buy and hold? 

What do you mean by "traditional 6-month financing route"?

If you ever see someone offering terms that are too good to be true, you might as well just post your SS# and banking information on IG.

This is done via a traditional cap table.

I've also used traditional loans through regional banks and a few SBA loans. 

Instead of a traditional down payment, I would give them some money (maybe just to bring the loan back to even).The upside if taken over the loan at the current balance, with some rehab and hopefully getting the front lot back would be a nice ROI. 

Unlike banks, which offer limited loan options, brokers have access to a wide network of lenders, including niche and non-traditional financing sources.Here’s what they do:Assess your financial situation to determine your borrowing power.Compare multiple loan products to find the most favorable terms.Negotiate rates and terms with lenders on your behalf.Guide you through the application process, ensuring you meet all requirements.Example: Suppose you have a lower credit score or unconventional income sources.

You can put a mortgage into a "trust: without triggering a due on sale but again contacting your bank/lender is the best route to avoid any issues.Some banks/lenders or servicing companies change guidelines and even a trust may require other paperwork but the attorney usually facilitates that to be safe.  

For us in the seller financed note investing world, we are often looking to find value in a deal that fell outside of a traditional banker's lending box.
