Typical items to include in a partnership agreement include1) How income, losses will be allocated to each partner2) What would happen after the result of an unforeseen event(ex. death of a partner)3) how/when the partnership will disolve4) Who will manage the partnership5)etcOnce you have the partnership set up - the partnership will not be eligible for conventional financing.

Otherwise, you should be able to go up to 10 loans through conventional methods.

FHA, VA, USDA and conventional loans are all available for manufactured DW homes, new or used.   

Therefore our real estate agent told us it might be difficult for the VA loan to be approved also we cannot afford conventional with (20% down). 

I think Goldman Sachs Investment claimed the summer is almost over, tight inventory and higher interest rates by downgrade both RDFIN and Z.With that being said, Zillow stocks maintained at $64, market cap is 11.9 billion dollars.

Or would it be better to maintain the current low VA rates and hope for the best on new conventional financing?  

The limit for conventional loans is 10.....as long as You and the property qualify, no problem.

I can hook you up with the guy I work with there and he can show you their inventory (which they actually keep more than just a couple at a time).

Availability of inventory and pool of buyers will tend to dictate demand. 

At some point a surge of vacancy seems logical as more of the displaced homeowners resettle into their homes and the new inventory keeps getting added.The wildcard of it all is, how much new demand that will fill the vacancies at rates based on projected population growth.
