Sub 2 or Lease Option?

[TC Greenwood]

Hello

I have an existing house that the owner is willing to sell (she owes 75k) and it needs 20k in repairs. I want to make sure I protect myself but my plan is to fix it up and put it on the market ARV is 130k.

The repairs will take about 6 weeks.  I normally pay with cash but I don't have the cash to do all of it right now.  So I talked to her about seller financing and she is fine with that.  I need to make sure I pick the right kind of financing to make sure I am good.

Any help would be appreciated
