Purchasing with lease/option?

I met with a seller today and need help.

ARV=$84,000
Repairs=$6000

I offered them $53,000 in cash or told them I could pay $60,000 if they would allow me to buy on a lease option. They jumped on this and are onboard. I have only “sold” using lease/option, but never bought.

They are 1 payment behind, but say they will get caught up at the beginning of the month.

Do I have a deal? How do I protect myself from going in and repairing the house only to have everything fall apart?

Anyone in Montgomery Couny, Texas with EXPERIENCE in creative REI interested in teaming up on this one?

Thanks,
Kevin
