The plumbing was shot, so we gutted the place and began from the foundation.

It has electrical, but no plumbing.

Also remember it will take time to get them done, during which the home is vacant and not on the market.People shop with their eyes-so many don't care about stuff that is really important (plumbing, electrical, roof, etc). 

New mechanicals (HVAC, electric, plumbing), kitchen, bathroom, adding a 1/2 bath in basement or 1st floor, new drywall, floors, paint, etc.

Rehabbed most of the stuff myself except for supply lines in the plumbing.

Insulate, add electrical, mini-split ac, and possibly plumbing, as desired, drywall, tape and paint, put built-in cab's on one side if you want, hang the tv, speakers, etc, install bi-fold/multi-fold doors on the side leading to a patio, and replace the garage door with an insulated one keeping the track and removing the motor, or install a carriage type garage door into the existing garage opening.

AC, electricity, no plumbing.

Any other possitive factors  - stable tenant base  - alarm systems  - regular checks on the property  - no pets  - Lead safe certification  - newer roof, plumbing, electric, etc..Anything to balance off the lossesBe prepared that it may end up in a non-standard (surplus lines) market for a couple of years.If you did not have flood coverage before, see if they will continue the current policy if you get Flood coverage and increase the property coverage deductible. 

Plumbing company doesn't have a payment plan.

Info from roommates on things that happened before I moved in: Worked on the plumbing while people were in the house, and the water was off for 1-2 days.
