I was willing to pay the 630 total including the 5%buyer premium. 

Because of this market shift, at least from what I've been seeing on the MLS/Zillow etc, 4plex prices are coming down (great news for first time buyers).

All the "as is" and "buyer must order the use of occupancy"..etc criteria makes me hesitant to buy foreclosures.

If am the buyer and my name is Joe Patterson, I assume that goes on  line #1, .....but then what is #2 and #3 for?

You'll also change the dynamics of your buyer pool.

Here on BP you can do that by adding a picture to your avatar.Understand that beyond understanding the technicalities of rules and regulations, real estate is about market conditions and helping people to get to yes.Get to know your target market like no one else.Develop your ability to empathize what's going through a buyers head and a sellers head and figure out what you as a real estate agent can do to address concerns.Neither of these are limited by your age.Good luck!

What's are some criteria that cash buyers look for when looking for a wholesaler in the South Georgia area?

The sale fell through due to unreasonable buyer demands following the inspection - first time homeowner who essentially wanted a "brand new" 70 year old home.

For example if it is going to be a sandwich lease you have to leave enough room in case a tenant/buyer decides to bail on you after 2 years.  

In general there are fewer buyers for land.
