I bought my neighbor’s house and just wrote out a one paragraph agreement (no template) saying: X is selling house his house to me and upon closing I take possession. I can barely spell my name besides write out a legal contract but it passed the bank and necessary lawyers.

The only issue I had was that the lawyers didn’t like how the abstract described the propriety lines and I had to pay around $4k for a survey and wait 6 months. That really pissed off the seller and me.
