Ashwin,Few questions -1) Is the developer assessing ur land value at 15% of total project cost?

Another thing that helps maximize the strategy is the amount of cash inflows a person has each month or the amount of inflows because on a revolving line the interest is calculated daily or on an average daily balance like what  depending on the LOC (line of credit).on the All in One or AIO loan from CMG the interest is calculated daily and swept or added to your balance at 12AM each day so all your paychecks, rental checks from rentals, or stock dividends, distributions from your business, or etc can be used to lower your balance by 12AM each day and lower your total interest costs.Most HELOC's or lines of credit calculate interest on the average daily balance which is like all balances within the last 30 days divided by 30 which is not as efficient as the AIO's daily sweep but close.The third method of interest calculation is the 30 year fixed which amortizes or calc's interest every 30 days or month so extra principal paid into this loan after the 1st of the month doesnt lower the incremental interest on the reduced balance till next month.

It's 1,344 finished single family manufactured house built 2005 over a 1,344 sqft basement with 9' ceilings (2,688 total sqft.)

We are planning construction of two 24-story towers with a total construction floor area of 70,000 square feet over a two year period.  

The total of these land contracts/mortgages is about $780k. 

(I would have to provide $120,000 for 20% down payment, leaving a total loan amount of $480,000)...The $480,000 goes to the seller (more than half of the asking price which is more than what he requires for owner financing)...The seller then credits back to me $120,000 at closing, creating an owner financed loan of $240,000 and giving me a no money down deal.

The upleg for this 1031 will be roughly a 60M total equity position with about the same amount of debt; i.e. a total cap of $120m and will be using all of the proceeds. 

Maintain a decent cash reserves to cover vacancies, maintenance, CapEx, and mortgage payments encase of total income loss.
