(First Deal) Is this a good deal/opportunity

[Colin White]

Long-time lurker. First-time poster. Don't eat me alive. I feel like this potential deal structure is different from most which is why I'm seeking more advice/wisdom. 

It's a double wide manufactured home, 3/2, on land near the lake, 1 acre, worth about $110K to $125K. It's off-market and I'm getting it for $85K, no interest, seller-financing. 

It needs little repair/work as the owner is a contractor and his daughter initially lived in the home, so he's kept it up-to-date. Roof was recently replaced 4 years ago.  

The manufactured home currently has tenants which are paying at least $200 to $300 below market rent. The catch is the terms.

I'll repay the $85K over 5 years with just a one-time $10K payment this year, 2025 - 2028 it'll be a one time payment of $9,600 each year and in 2029 a balloon payment of $45,600.00. 

Possible exit strategies are a quick flip on the MLS, the home has been moved so I think that excludes FHA financing, but a conventional loan is still available.

I could just become a landlord as well, or get rid of just the manufactured home and keep the land. I know the cash flow is weak, if not potentially negative, once insurance and taxes are included and that may immediately make it a bad deal for some investors. Of the 4 REI profits, I still think there's a little light with principal reduction and appreciation, not sure on tax benefits. Any thoughts, run away, am I missing something? Thank you
