I also have a buddy that works KSN and they are great with delinquent homeowners for sure and for fighting tax assessments. 

@Ouman You If the property was her primary residence, yes, it will not qualify for 1031 exchange treatment.

I am selling 2 rental units to purchase unimproved land to be used as my future primary residence.

Live in it long enough to qualify as a primary residence  then sell without having to pay capitol gains.

You need to clarify on if that is going to be your personal residence, or you meant your first investment property. 

The FIRPTA Certification requires that if a selling party is a non-resident for purposes of U.S. income taxation, a portion of the sale is withheld.  

He and his buddies trashed the place in a matter of 3 months.

I have found in this area they tax foreclose after about 10 years if you offer them above the delinquent amount most are willing due to them not getting anything if it forecloses and not using it as a residence anyway.

I currently reside in Southern California and do not plan on investing in SoCal due to funds and the current overall market out here.

Lastly, the requirements and ease of getting more-or-less conventionalfinancing also will be determined by your intended use of the property.If you are buying it as your primary residence and will be living in it, then getting financing will be a lot easier than if you were buying it as an investment property to be rented out.
