I'm just looking for the brokerage that I can visit and talk with and eventually call it my home brokerage.

There are three costs you must be very familiar with LandSoft (carrying costs, entitlements, impact fees, association if applicable, maintenance, etc)Hard (home construction as well as site construction)Have done numerous MF and SF developments. 

Be sure to check out all the areas of the site.

There is a park manager that would live on-site to maintain the park and is willing to stay on and help expansion if necessary.Half of our team is not sure that we should purchase since it is in a small city with little plan for growth.

I’ve found a few good articles on Bigger Pockets – but honestly it seems like there is way too much information on this site to shift through6.
