Welcome to wholesaling. You should read through the wholesaling forum extensively because a lot of the questions you want to ask as a wholsaler will probably be there. As, a wholesaler your customer will be the rehab investor\flipper.
Some basic questions I can think of are...
1) What is your price range?
2) What areas do you prefer to rehab in? Which areas do you dislike?
3) Wjhat type of houses do you like? 3/2's? What type of houses do you NOT want
3) Are you a cash investor and how quickly can you close? (i only deal with rehabbers who have instant access to capital)
4) How many deals can you handle? Can I bring you 3 or 4 houses? 10 or 20? (I've had investors tell me that I will run out of deals way before they run out of money.)
I may have forgot some but these are kind of basic.
Right now I deal with almost exclusively with 1 rehab investor. He's got deep pockets. He told me he needs 40 properties this year so I just bring him whatever I have and we have a nice relationship.
I just cashed a $3k wholsaling check on Friday from a guy who called off a bandit sign about an estate property he inherited.
Should have another closing next week for $5K.
The trick is to keep the deals coming in.
Remember that every deal is not a deal. You have to go through the duds to get through the deals.
Happy wholesaling!
