Property is not cash flow positive when rent x 75% then what calc

[Account Closed]

If a property is not cash flow positive when rent is multiplied by 75%, then how would a conventional lender add this calculation into your DTI?

Example $4000 a month 12 month lease signed, actual monthly debt is $3271 a month including P&I, Tax, Insurance, *no HOA. Multiplying rent by 75% would equal $3000, but total monthly debt obligations for this property are $3271.

(This property is a future tear down, a land development play for the future.) I'm wondering is there's a way to easily figure out how conventional lenders would factor this into our DTI calculations. I have another property that might be in the same boat (again, plan to bulldoze and build a spec at a later date,) it's 75% ratio is only $1.09.

Any insight would be greatly appreciated. 

Thanks
