I have defiantly learned my lesson, going forward I will not make the mistake of trusting another person to take care of my house as well as I would. 

Unless vets are considered to be so special that credit scores do not matter a 500 score will be no where good enough for any conventional bank loans.I would rent, with luck you may find a mom and pop landlord that does not care, then work to repair your score over the next couple of years.  

most likely laziness or misplaced trust. the only person who you can reasonably expect to care for your property is you, and a strongly written lease is your first line fo defense against damages.

Our family's goals are to pay off our consumer/student loan debts and have enough cash flow that I can cut back my hours (maybe to 0 hours) and travel full time in our travel trailer for a few years and then maybe go back to work but probably not.

I definitely wouldn't try to cut the realtor out of their commission.

Will she charge me or can I just cut her something out of the deal?

You have to be careful with towers.

I will be careful, didn't know there are a lot of scams from the Phils.

Last but not least, be careful promising a rate of return in exchange for an investment.  

The market does not care how much you paid for the property or how much you overspent on the renovation.
