Hold long term as rental or sell now

[Virginia Jones]

A couple months ago I bought a foreclosure for $55,000. I've got a lease signed for May 1 at $750/mo. They are interested in buying the home from me. I work at a bank and if they qualify, I could get them a mortgage to buy it.

Once everything is ready, counting closing costs, I'll have spent around $11,000 rehabbing the property.

Would it make more sense to keep this house rented or sell it?

Appraised Value/Tax Value = $87,000

Purchase Price = $55,000

Rehab + CC = $11,000

Monthly Rent = $750

At what selling price would you all say it would be better to sell than hold?
