@Brady Herbaugh- thanks ...a house hack where you live in the property you buy is the best step to take for your 1st investment...make sure you get pre approved  for a loan before you begin to search for a property  

Mobile home parks can provide consistent income, and if you manage it well, they could become a significant source of cash flow.

If financing part of the replacement property(ies), secure pre-approval.

An auto dealer who owns an empty lot across the street from his establishment wanted to get approval for a parking lot to park his cars in the lot rather than on the sidewalks when the city cracked down on it.

Mostly duplexes, however we just finished an 11 unit build and have approved plans for a similar 7 unit project coming up.

I would say compare terms, seasoning period requirements (Assuming when you mentioned construction loan you're talking about a rehab project), response time of your rep, learn as much about their loan underwriting and approval process as you can.

Keep in mind that the changes made to STATE approved contracts will vary.

@Frank Rolfe's Mobile Home Park Bootcamp is the gold standard!

So I have an llc and business account set up for that llc, but I just bought a duplex with an fha loan which isn't in the llc because I couldn't get fha approved for the llc.
