However, at this early time in my life, I'd like to start at a commercial/development real estate investment firm that is established. 

Great established neighborhood with recent comps.

Perhaps a different tax credit program other than the low-income housing tax credit program should be established to address this increasing need, yet that type of program would be a drop of sand in the ocean regarding the overall need for it.Thoughts?

It all comes down to establishing relationships with a potential buyer and building a rapport.

@Tristan Bexell I don't see any reason not to buy a multi-plex property but you could get such better deals on the financing if you established residency.

I want purchase my first mobile home park, do think I need to establish an LLC at this time.

Basically I'd take an established cash flowing property and find an investor that would buy into it for a return and possibly an equity stake.

The few commercial lenders I have talked to wanted to work with established businesses.

They are established and still have great properties for rental income.

The street I'm on all the horses are basically the same except furnishings and they currently rent between 1300 and 1500 based on the market when lease was established.
