no transportation, 3 duffel bags of clothes and a Dog. 

If you have trouble unscrewing them use a wash cloth soaked in white vinegar and wrap it around the element for 24hrs.

It's a whole house rewire including new service drop by the power company - - very expensive - - but mandatory for safety as the cloth insulation has rotted away.Plaster was applied over a lath base and you strip the walls & ceilings down to the studs to replace with today's wallboard.Bet you had no idea of what you've gotten into - - sorry to be the bearer of bad tidings.

My understanding is that there are practical concerns in Florida (with all the rain / dampness tile holds up much better).I suggest you take a look at rentals near your duplex and see what's typically renting and for what price.

If you are going to install one in or next to a shower, make sure it is rated for "damp" locations.

Most people looking in from the outside think you have stacks of cash and spend your days shopping for high end clothes.

Haven't had any issues.I've had termite service done to several of my houses.There are 2 types that is very hard to get rid of (damp wood/dry wood) since they don't need to touch the ground, and the house might need a tent.Good luck

Walls or damp to touch, and some clothes are now moldy.

Once you add-in the cost of utilities (especially heat), furnishings (couches, tables and chairs, beds, sheets, towels, table cloths, pots and pans and plates and silverware, napkins, toilet paper, TV's and radios, washer and dryer and refrigerator - yes, it's common for a long-term SFR not to include a washer, dryer, or refrigerator - etc, etc, etc), plowing/lawn/trash (or HOA fees), cleaning, extra repairs and maintenance (I promise that a long-term house renter takes better care and causes less wear and tear than a revolving door of vacation renters), turnover management and screening, etc, etc, you are not making any more with the vacation rental than with the long-term SFR where the tenants pay all the utilities (possibly with the exception of water/sewer), and take care of the lawn and snow, and provide their own furnishings soup to nuts.

The unit is still fully furnished, including clothing and food but no one is staying there.
