But my wife and I had some significant health issue and our credit and income won't qualify.So I am thinking of selling. 

@Trevor DickieYes, the 2-yr gap rule is a problem.If the sale of your current home is not due to some unforeseeable circumstances - like job change, health etc. - then your best option is to pay tax on the condo.

She’s got mental health issues.

.—(1) The landlord at all times during the tenancy shall:(a) Comply with the requirements of applicable building, housing, and health codes; or(b) Where there are no applicable building, housing, or health codes, maintain the roofs, windows, doors, floors, steps, porches, exterior walls, foundations, and all other structural components in good repair and capable of resisting normal forces and loads and the plumbing in reasonable working condition.

However, due to a family member's health situation, we were forced to move back to San Diego after living in the house barely 6 months. 

I am more concerned about the overall health of the city the school is in.12 month leases. 

In one of my properties the tenant left a trash can outside before 12:00, this was  considered a health violation which is also a misdemeanor.

He would need a licence and will never qualfy for health reasons.

You could also focus on the great financial advantages of renting/down-sizing (travel more, no more yard to care for/repairs, buy an RV, visit family more)Host a senior-focused event at your facility (maybe show an uncut version of Woodstock haha) or live music, a Social Security expert speaker or Doctor to address health issues, a fund-raiser, art show, etc. and hand out flyers with a special "one month free" coupon attached Have exercise classes for seniorsWeekly bingo nightsPromote your events for free on community calendars, newspapers, seniors sections of papersPrint door hangers and get some kids to hang the door hangers at trailer parks, older communitiesEncourage your current tenants to invite friendsRent a 15-passenger bus ($50) and offer free transportation to key eventsSponsor events at senior centers in the areaCo-Sponsor service club (Rotary, Kiwanis, etc who have many senior members) eventsPut up banners and balloons when you have eventsI hope at least a few of those ideas might spark some interest.

@Russell Brazil My initial intention was to occupy the space and make it my permanent residence, however my fathers health deteriorated shortly after I made the purchase, which is why I made the decision to stay with my parents and try and rent the apartment out, rather then sell and take a loss.
