Am I buying it after it's been renovated and rents have been raised?

Speaking with my brothers this past weekend we talked about trying to keep the house in the family by buying it from our cousins.

Investment Info:Small multi-family (2-4 units) buy & hold investment in Columbus.

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 know you don't have money for a downpayment yet, but when you do, rent out rooms or buy a duplex or triplex and live in one side and rent out the others.  

Purchase price: $550,000 Cash invested: $145,000 Sale price: $915,000 This was a home run for a long term (5 years) buy & hold investment property (I specialize in this area). - Initial investment of $145K (DP+closing)- It had one tenant for 5 years and 3 months (no turnover), and the tenant paid off the mortgage and expenses in those 5 years.- I spent around $30K to do upgrades before selling.- Sold it for $915K after 5.5 years (received $442K at the closing)- Did 1031 exchange and bought 8 SFH in NE & AL worth of 1.6M (brings $4k/months income now) What made you interested in investing in this type of deal?

Looking to build an ADU on my property, considering buying a prefab or having a contractor building it.

Then you can help them find a new place to buy or just keep renting. 

.#1 tip I'd give if you're buying existing (or building) is to call the assessor and ask specifically what the new assessment will be after improvements.

Any chance you could send me a copy?
