I have two properties (exact same property just across the street from each other) one is a seller finance that is coming to the end of its contract for balloon payment and the other is a fix and hold Interest only loan that is also coming to the end of its contract for balloon payment.

That's exactly my point.

Key Factors for a Good Seller-Financed DealCash Flow: Rental income should exceed monthly payments (PITI) by at least 1.25–1.5x.Purchase Price: Compare to ARV and market value for fair pricing and equity potential.Interest Rate: Aim for competitive rates; higher rates must still allow positive cash flow.Amortization/Balloon Terms: Favor longer amortization and align balloon payments with your exit strategy.Down Payment: Lower upfront costs reduce risk but should meet the seller's expectations.Flexibility: Seek no prepayment penalties and fair late-payment clauses.Property Condition: Ensure the property’s condition matches terms through inspections.Seller Motivation: Assess the seller’s willingness to negotiate favorable terms.Exit Strategy: Have a clear plan for refinancing or payoff at term end.Portfolio Fit: Ensure the deal aligns with your financial goals and risk tolerance.Vetting multiple deals and consulting professionals is crucial to making sound decisions.

Quote from @Dylan Gomez: I inherited two homes, both were paid off one was livable, and I now live in it, the other was a rental in TERRIBLE condition.

That's exactly how I did my first two deals...

I intend on sending the tenant a bill for the exact repair cost as "additional rent" (per the lease) instead of evicting in the winter and deducting from the security deposit.

This is exactly what I mean. 

She moved out exactly a month if stay there and they left the place filthy also her son is not on the contract and I been told that many of them were living there while contract has only two people.

All of these houses were purchased in distressed condition and remodeled extensively.

Exactly the kind of advice I am looking for.
