Thanks @Brad S.. I'll have to definitely give this to a lawyer to review. They sent a contract over and under additional terms it says, "Seller to owner finance. Buyter to put $13,500 as down payment. Balance of $76,500 to be divided into 8 monthly installment payments of $9,52.50. Monthly payments to be made by buyer the 5th month and begin April 5th, 2022.
Seller to pay a 3% commission"
There is no language in there about penalties for late payment of failure to make final payment, which I believe should be in there.
Yes, the other thing I have been wrestling with that you mentioned is developing the property myself. I believe I can make a good profit from building a spec home on it, but the negatives are having to risk the $250k into build it and dealing with volatile building costs. I do have my Builder's license, but it would be hard for me to be on-site as it's far from my home. I have talked to some builders and they are quoting me $150/sq ft - $200/sq ft. If I was the builder, I could probably do it for $125/sq ft. as I would cut out the intermediary. But that extra cost might be worth it to avoid headaches. I suppose this is a good problem to have.
