And have you already lined up financing (either with bank or HML)? 

Do you have a team in place at Fort Lauderdale like cleaning crew, plumber, electrician, key drop off?

Bottom line.

Put property management in OPEX, above the line and put CAP X below the line. 

If you're still short of the 12 months, keep it clean and simple.

Hold her to the lease and advise the ex to get a restraining order, problem solved.Bottom line is that by her leaving the lease is not legally broken unless he leaves as well.

However one option that I have is to get a line of credit at 0% APR for up to 24 months.

Unless you are thinking there are other things I should be thinking about other then vacancy, cleaning, minor repairs?

This just happened to a fellow investor who's tenant abandoned and damaged the unit--he used a lease he found on line and was unable to go after the tenant for damages. 

I got it all cleaned up (special crime scene clean up is expensive thank God for insurance) and was terrified it would not rent and that the neighbors would run off any prospective tenants with the story.
