First, I recommend you concentrate on properties that YOU find attractive as an Investor, rather than trying to work out why other Buyers might like to pay you more than you Contracted, for a property that hasn't particularly appealed to the Investor-in-you in the first place.Consequently, finding a Lender who will "cover" you by lending the money to you IF you can't track down another cash Buyer before "closing" time, becomes a win-win for both Plan A (Wholesale) and Plan B (Buy)!
