Things to consider would be down payments and renovation cost.

New constructions in the neighborhood are selling for a significant amount above construction costs (double or more the market value of the land).  

Hi Vadim,There is a conventional/FHA program called a '203k rehab loan' which allows you to purchase a property and wrap in ALL renovation costs INTO the mortgage, so in your example above, the total loan balance would be around $70,000. 

I am looking for a template that will calculate the a maximum  cost to purchase a fix and flip , with a variety of financial options and then a template to manage all project costs.

I am considering doing this deal with no agents on either side to save money (savings the seller would pass on to me) - my buyers agent actually suggested that when I explained the situation to her and that I really only needed basic transactional help. 

The logo on your card makes no difference.

I build at simple closet with accordion doors to make it as some and cost effective as possible.

HECK NO!!  

You mention you have no experience in these types of parks and your first deal you want to take down 100.When I was working for a GC we did a condo project for a developer who never developed a building before and he sold his company (it company) and used the entire amount to develop real estate.He ended going bankrupt because his inexperience with his experience and his designers and every mistake they made was multiplied by 150 since that is how many units there were.

Is it a no go?
