By showing yourself around the neighborhood, someone may not immediately be interested in selling, but they'll remember you over the letters they threw in the trash.I recommend listening to the BP podcast and start reading some real estate investing books to start off.

Now it is time to get serious and make this grow. 

Remember to fall in love with the deal, not the property. 

Remember he pays all costs/legal fees for drawing up th emortggae.You need a significant non refundable DP to cover your costs if/when he defaults.

Of course you have to remember that PA does not recognize 1031 at the state level. 

@Joshua McFarlin when your multiply the expense ratio remember that the actual number is inverse.

Remember the bank or mortgage company will have a mininmum that they will take, but they need the property off of their books also.  

Remember, just because you may have a longer pay period (30 years instead of 15), doesn't mean you are paying more for the property. 

What do you have them do for you that allows your business to grow?

Just remember to factor in the wholesaler fee to your overall deal if you will be paying this fee directly to the wholesaler.
