I figured I would have to figure out how to overcome that since I'll continue moving around every couple of years with the military anyway.

MINDSETYou need to retrain your brain and change perspective on the filter through which you are viewing things.We all have obstacles to overcome and many of us started from nothing.

I don't know if someone will file a forged document or whether an adverse claim might be made on one of my properties...issues that would cost me time and lots of money to cure, so I buy insurance for those risks.

,maybe along the borders of two states or country's there are little sections where it's not sure who controls it. one instance would be where a river was the boundary but over the years it moved Or here in Oklahoma I own a few acres in one county and there is a section of land between me and a neighbor both our property's have been surveyed so we know its there and also know of others just like it Its never been on the tax roll and its not claimed by a tribe as Indian landI guess it would be called abandoned land And someone could use The Law of Adverse Possession

The math has overcome my emotions, however, and I'm ready to get serious.

I do not know where you received that type of information but it is false.Now there are some very risk adverse investors that only put 50% down because if the market shifts they still have equity and will not be in a crunch.

How will you overcome those obstacles or what will you do if you can't?

The only way to overcome the flag of market rejection is drop below market price, effectively getting your client below market value for their property.  

Look at your sales script, and see where there might be some mention of only one buyer.The objection can probably be overcome with a simple "There can be only one buyer for your property, and he's sitting right here in front of you?"

@Shane ForrestNot sure if there one magic bullet to make you overcome fear.
