My guess solely looking at your numbers is that it's an older/distressed property which means you have to account for more costs in capex. 2nd thought being it's not in the best of neighborhood then you'd have to take into consideration lower quality tenants/ neighbors and maybe increase expected vacancy and late payments.

Could be a business decision based on keeping long-term high quality tenants rather than risk the costs on turnover. 

I make sure I screen each potential tenant thoroughly (background and credit checks) and require references.

Buyers expect premium finishes, so skimping on quality can hurt resale potential.

You screen applicants because you don't know them!

Quote from @Andrew Betts: Hi Michael - We own and manage homes in Solara, I can recommend it for a strong ROI, and there is full access to the clubhouse, and better quality food and drinks there, than at other resorts. 

You also need UX, support, quality, a million other things.
