Seller Finance Deal- good deal or not? Please help, appreciate your thoughts!

[Kantcho Traykov]

Hello everyone. My wife and I have been looking to invest into real estate for a while now and this would be our first time dipping into it. Our plan currently is to get a piece of unrestricted land with utilities on it and put a tiny home on it and Airbnb it. I have found an off market property from someone that we were referred to by word of mouth who is selling a lot in the North Carolina mountains, the lot is a little over half an acre. House pad, gravel, and all utilities are already in. It's build ready basically. He is asking for 65k and is also willing to finance the land. He is asking for a 25k down payment and then a 5% interest with a loan for 7 years. And he is also charging a 1 time yearly fee of $300 for sharing his well. So that means that the payments will be pretty high every month, however what are your thoughts on this? I appreciate everyone's opinions. My wife and I are new to this, so we are trying to find a good deal to go into for out first investment. Thank you.
