I’m always looking to connect with like minded individuals.

If you are able to get a traditional loan only qualifying yourself or your wife individually, that allows you to get more loans later (20 vs 10 if you do them jointly). 

Friend has good credit more working capital.Should I go LP for each individual investment?

Is there a way to determine whether a real individual is bidding against you or that it is auction.com algorithm seeking to boost the price?

You need to make sure the individual is an actual licensed attorney in the jurisdiction in which you reside or in which you plan to operate your real estate business. 

Regardless of whatever strategy you employ, be sure to have reserve funds on hand which will enable you to pay the monthly expenses on the asset if you lose your tenant or if they can't pay the full rent.  

This enabled me to beat out other interested parties and secure the property.

I think no matter the lending environment, you will always find someone who would rather deal with an individual rather than a bank.

While I agree with the maintenance, I think utilities would depend on the individual mobile home's energy efficiency vs. the average energy efficiency of homes in the area.

Hoping to connect and evolve with the many individuals that have helped make this opportunity so successful!
