Moving forward, the formula's make sense to me.

The only way to know that the formulas are correct is to create your own from scratch and test the crap out of it.

I know the standard formula, or used to be, was to offer 70% of ARV minus repairs.  

DCR (Debt Coverage Ratio) = For every dollar that you take to pay your mortgage, you make this number back in return (formula is Annual Rent / (Debt Service + Insurance + Property Taxes + Property Insurance + HOA if applicable)3. 

Then continue that success formula withe every liability you purchase.

that formula means you never are on title, you never own anything, you don't have closing costs, etc.  

If the house is worth $200,000 and the loan is $100,000 and you simply paid off the existing loan, with out follow the formulas established in the Statute, you will receive fan mail from the Attorney General asking for your presence at a party being held in your honor, and oh, we want your attorney to come along with you.There are a lot of hungry attorneys out there taking cases of "distressed" homeowners pro bono, since you will end up paying their fees.

Just fyi for others. myfico.com :Does the formula treat all credit inquiries the same?

Definitely can use some of them for my purchases.You are most welcome - it's good to be able to think of 5-10 different formulas to put together a contract  offer.

Different banks have different pricing formulas.
