Why do you think they "lost your file"?

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

I'm thinking that I need to go to an electronic receipt tracking system, I've been doing it old school all these years - dump them on my desk, some month down the road go through them all and file them to folders for reach property, start a new folder each year. 

@Ben Johnson Not enough info here, but based on what you wrote, you have $5,000 in monthly cc interest and probably $3,000+ in principal.  

I would look for a bunch of Sub To Deals with 2-3% interest rates ...... then rent out for cash flow and huge equity build up when rates are really low (check out amortization schedules and compare 2-3% vs 6-7% with the same balance and length of time - check out the principal portion each month - the lower the rate the higher amount goes to principal PLUS better cash flow).

Lien is filed and recorded and then do nothing until it gets paid or property is sold and is paid ..

Borrowers are not allowed to complete any of the work themselves as sweat equity.Loan to Value Calculations:The original principal amount of the mortgage may not exceed Fannie Mae’s maximum allowable mortgage amount for a conventional first mortgage.Purchase: For a purchase money transaction, the LTV is determined by dividing the loan amount by the lesser of the “as completed” appraised value of the property or the sum of the purchase price of the property and the total rehabilitation costs.Refinance Transactions: For a refinance transaction, the LTV is determined by dividing the original loan amount by the “as completed” appraised value of the property.Eligible Renovation:There are no required improvements or restrictions on the types of repairs allowed.

We have a partnership entity, so it has to file separately and needs balance sheet accounting.

Locking in a lower interest term loan will also force you to get the principal down as opposed to just making minimum card payments every month that allow the balance to keep growing.

Ignorance IS a defense in residential, and one a party can file a class action lawsuit on because that's much of what just happened nationally.
