This creates a negative initial position.

Quick question on those who have done seller financing:- Buying a 0.3 acre downtown fort lauderdale multi family, negotiated an around 1M price w lot of development rights, double lot. seller got it way back early 90s for pennies- got good credit 800+, w2 job etc put 40% down and mortgage bank offered 6.62% 30yr fixed (CF negative as this would make current rent roll not too much compared to the PITI)- property is in ok condition, needs 20-30k repairs which seller OKd, and all 3 tenants are month to month, pay bit under market but also ok- seller would like to do seller financing, interest only at 5.75%, 30yr amortization at 7yr balloon (CF would be positive) - id be paying some principal as well, just to grow some equity- buying this deal for the future development of the area (las olas, kushner broward crossing) so not really worried even if we overpay for it now, but never done creative finance as i always relied on a strong W2 job to get good loans but obv im used to 3% 30yr rates from covid times not this 6+ environment..Goal is to hold the property 3-5yrs, and then actually develop it or sell half the land / refinance, pull out HELOC if it appreciates.Questions:1) What does he know that i dont? 

I have not had a single one of the negatives people seem to think is above.

The US is running a $1.8 TRILLION DEFICIT (negative cash flow).  

Breaking news: events in and out of our control will affect real estate both positively and negatively.

While I don't want to get myself into a negative cash flow situation- appreciation is the bigger deal for us. 

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

Although, my company would be LISTED in the foreclosure, there would be no negative impact on me other than possible rumors about me being in dire straits.#3.  

Verifying last 2-years of rental history and income/employment extremely important to find the “best of the worst”.Tenant Default: 20-30% probability of eviction or early lease termination.Section 8: Class D rents meet program requirements, often challenges to pass Section 8 inspection.Vacancies: 20%+, depending on market conditions and tenant screening.Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciation.Where did we get our FICO credit score information from?

In your proposed case you would be compounding this negative position by taking away the best source of financing for a large percentage of potential buyers.
