Income source protection is a reality that continues to spread and I don't care fight windmills; much like the support animal nonsense.  

. - for as narrow or as wide of a net you may want to throw out for your own “real estate investing.”But if you should still have an inclination to trust some guru with a paid mentorship, I’d suggest to go above and beyond their standard contract, which will likely stipulate what you owe them in far better terms for themselves than what they owe you in return for your money: I’d ask them to stipulate - in writing - what “mentorship” your money (at each level of a “workshop”/“education” they expect you to pay for) will actually get you, and for how long.

On top of the 'commonly used' investor filters like 2+ years back taxes, recently inherited, etc- I loved some additional possible/ unique filters like number of structures on a parcel, min/max land sq ft, initial purchase price, and ability to narrow down to very specific areas on a map.

Obviously narrowing down those markets for your criteria is the next step.

There are some hatemongers that don't have a clue about law and this line of business but deliberately spread false information about wholesaling on BP to intimidate and mislead.

Seller finance deals work when one of the following situations is present1- property can’t be financed with institutional financing usually because property is vacant (commercial property) or in bad condition2- seller will only accept an above market price for the property and by offering seller financing opens the universe of potential buyers to include people who wouldn’t qualify for financing3- seller is able to obtain a “piece of the action” from a buyer rehabbing the property and hence ultimately obtain a higher price.4- the seller has an existing low interest rate mortgage and wants to “wrap” the existing mortgage into a seller financed higher rate mortgage and pocket the differential 5- property is an investment property, seller has a low basis in the property because of depreciation, and wants to spread out the taxes due.Are you thinking of trying to purchase with 100% seller financing, or are you able to /willing to offer a down payment of say 10-20% .  

Depends on the spread.
