He isn't a motivated seller.If it will rent for $1900  a month, that means to make money you have to have a payment that includes, principal, interest, prop taxes, insurance, at less than $1400 a month. $190,000 at 3% interest is P&I $801 + prop tax plus insurance a month.

Security deposit will take care of the last month of unpaid rent, but I'm considering filing a small claims court lawsuit to get a judgement for recoverable damages.

When you file your taxes at the end of the year the accountant is going to ask you for your receipts or what and how much you want to write off using deductions.

When you say "we," are you speaking about your business or your personal tax returns, or does your business flow into your personal returns because you file as a sole proprietor?  

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 hope more lawsuits will be filed. 

My suggestion is to simply file the BOI requirement.

Principal buy down that occurs with each payment met.3.

Because, the lender is entitled to know what risk they are taking with their money.That being said, on seller financing, if someone gets sued and loses, the lien/judgement can be filed at the county, (it's not automatic, someone has to prepare and send the paperwork) which the bureaus will pick it up on producing a credit report.

It has to be filed by either myself or an attorney representing me.
