Equity/Cash Investor needed ASAP

I have 80% of a condo conversion funded. I need 20% or 300,000- to start construction. This is a historical building in Salina, Kansas. This building qualifies for 45% of the cost of construction to be returned to the investor/builder. My figures indicate that will be worth $450,000-

Purchase Price of Historic Building $129,000-
Construction Conversion Cost $1,000,000-
Total Cost $1,129,000-
After Rehab/Repair Value over $2 million
How did I reach this conclusion?
Sale of 10 condominiums value$ 2,000,000- (asking price for each unit $200,000)
Historic tax rebate value $450,000-
Monthly lease of storefront for cafe/market $1000-
Association fees collected from condo owner $100 per unit X’s 10 equals $1000-

Hi valkie, Salina has a population of 50,000 people with a median income of $36k and median house value of $85k. As we going to find 10 urban professionals that want to spend $200,000 on a condo?
