Whats going on guys,
Let me chime in and give you my .02 cents.
Will you find off market deal on the MLS? Absolutely not, why? because the MLS is the definition of ON market deals. In order to land the best off market deals you will have to use the exact same methods that a wholesaler uses (if you are a flipper/buy and hold investor you simply just close on the asset instead of assigning it)
Nothing and I mean NOTHING will ever beat calling a homeowner directly. Keep in mind this is the cheapest form on entry since all other marketing methods are pricey.
Action steps: Buy a list (wholesalingdata.com comes with addresses and phone numbers, Listsource is great too but you will have to skip trace it) Make sure the property has enough equity or else you will be wasting money/time.
Make calls and find motivated sellers - keep in mind this is a lot of work and you may delegate this, however I would still recommend you do this to learn the ropes before hiring someone.
Best of luck.
