Glad your taking action. If you haven't given the address yet I would try and get in touch with the seller ASAP and ask if they would consider an offer or see what their plans are with the property. Tell them you are looking to buy ASAP ALL CASH (all loans are all cash). If they say yes ask more details about the property, condition, history, how it became like that, get to know the seller, their pains, why they cant upkeep the property, what happens if they dont sell etc etc.
If they would consider an offer NEVER give your number first ( I currently struggle with this). Ask 5 times 5 different ways to get it out of them to see if you both are close and not wasting any of their time. If its around 70% ARV, schedule an appointment ask where to send the offer/meet. In the mean time have your partner (wife) call every investor who they would recommend for an attorney and have them pump out a contract for you.
But of course you could continue to add value to the Wholesaler by bringing them deals and watching it work in action.
Good Luck
