They had to find a suitable new tenant or the remaining tenants needed to qualify based on 3x gross monthly rents.

. Second Home Requirements* Must be occupied by the borrower for some portion of the year * Must be a one-unit dwelling must be suitable for year-round occupancy * The borrower must have exclusive control over the property must not be a rental property or a timeshare * Arrangement cannot be subject to any agreements that give a management firm control over the occupancy of the property

Check your local laws- if you end up not moving in, the tenant paying rent until you find a suitable replacement tenant sounds fair to me- always include an early lease termination fee in your lease this way these situations are clearly spelled out if the tenants wants to exercise this option. 

Your customers are using the internet to save time in finding a suitable property.

@Allen Tracy - Curious where your research lead you on this post given it's been over a year; did your team decide on a market that seemed more suitable than others? 

I have to tailor my screening to get the most suitable candidates as possible since I am out of state and have to rely on external services (per fee).

If they are all wheel-chair bound, is your property suitable or will it require lots of changes? 

Firstly I would find a market that is suitable for you and showing signs of potential growth in the market.
