They are experts and an incredible local market resource.

I'm not sure why you'd target mobile home parks that's one of the hardest to entitle. if you want a scalable strategy for 10+ years stick to residential horizontal, apartment, etc that is more common for your market. 

Low or no down, seller financing and low or no interest with a balloon payment later is the holy grail (location, building condition, market also matter but it sounds like you have all that).

Quote from @Brandon Croucier: That’s a killer loan if they are actually offering that.Seems extremely below market value as even primary mortgages are higher than this right now.I would beware of a bait & switch on this. 

Quote from @Jaren Taylor: Quote from @Chris Mason: If you have the ability to market and raise money, then you secure the down payment, and do the normal commercial mortgage process. 

easy to build, rent, refinance repeat. might not be your market. look at the underwriting model. we underwrite every deal not only with fresh comparable but market economics change. land costs go up or down, construction costs go up or down, design modifications improve the property, comp sets can get more favorable or less favorable.

opens up a lot more markets and opportunities. you can build a 400 square foot unit or 4 of them or 3 of them or any size unit you want on any lot. 

In my market - new build duplexes dont cash flow well but are typically a great 5-10 year investment. 

(I assume trying to get free leads or market their name as the local expert.)If no one at your broker will help, reach out to new realtors.

Obviously you jam it all in the stock market for 11%.
