Of course, there is a fee for this, $250 and up, depending on the size of the dwelling. 

The prevalence of HOAs and rental restrictions in these burgeoning communities is a crucial factor to consider.

I had an experience with Fund & Grow where they work on the customer behalf to get approval for 0% Apr business cardsthey have a PoA to work on the behalf of the Client which is totally fine - however Lender do not like that and one of the Lender - FNBO - that approved me for a Business Card with $ 15,000 at 0% Apr for 12 months - after 2 weeks sent me a letter reducing my credit limit to $ 3,000 and upon calling the Lender they told me the reason of the lowering was due to the fact they found out there was a 3rd party pulling the request of the business card.I explained that to Limitless Funding Source and I asked - in case some like this happens - your fee is 15% to be paid within 48 hours from funding but if I got let's say reduced $ 50,000 to $ 25,000 or lower I will know maybe after 2 weeks - and in the meantime I already pay you guys 15% of $ 50,000 which is $ 7,500 for your fee and then I have only $ 25,000 available with $ 7,500 cost which is a 30% fee - are you guys going to refund me the difference?

Never built anything that small, as the incremental cost to go from say 800-1200sf is not a significant cost since the major factors in a home are the MEP's, kitchens and baths.

"So make sure you factor in holding cost, after closing".Max

So they only have to factor the build cost and other soft cost.The problem at hand with a new build is finding the land, the cost of the land, clearing/prepping the land and bringing utilities in.

Don't forget to factor in any shared expenses for the common areas, like maintenance or utilities, to get a more accurate picture.

The HOA fees eat you alive and then assessments could bury you.

I have a duplex, with a separate exterior space that I have been renting out to other third parties who wish to park a vehicle or boat there for a monthly fee.

Then you've got the license fee ($200ish), joining a local Realtor association (~$150) and national realtor association if required by your local board (another $150), the local MLS access fees ($300), e-contract software ($80/mo), E&O insurance (maybe $100/mo).
