Stuck - Two 4-plex rentals in Tucson, AZ

[Austin Nieves]

My partners and I bought two 4-plex properties in Tucson, AZ three years ago for $375k. They have been good cash flowing properties but the repairs have been more than we anticipated especially for our first investment. We want to take advantage of the current market as they have appreciated about $175,000. We want to 1031 them but two of the four investors have become independent contractors within the last two years making financing difficult for our up-leg properties. 

Any suggestions on how we can bypass these obstacle?
