We are looking at a duplex first probably and then single family.

I would request they pay rent the usual way, and then you can decide whether or not you want to utilize the app in the future. 

Then you have Huntington Beach State Park, as well as Brookgreen Gardens. 

This type of financing is more expensive and harder to get then 1-4 unit.

It went from a rundown home and outdated in every aspect to an up to date property that I rented for 2 and a half years then sold What was the outcome?

Quote from @Torrean Edwards: Early in my investing career, I had some success, but then the crash happened.

My inclination is to suggest paying back the PML 70% of the land proceeds (presumably $168K) at that closing and then hold the remaining loan until I sell the house. 

I have succesfully done this on IGMS PMS software.I would also make sure your email is listed on their VRBO account. you will then be able to get inquiries and messages on your email account so you know when someone messages.

After it closes, if he then gifts you back the profits, now that could be a second gift from him to you. 

I am exploring the possibility of purchasing an off market plot of land, building a modular home, and then selling it.
