They use the same colors and materials and truly spend the minimum time and money.   

As long as I know all I'm doing is cleaning the place, and my previous pictures are still a good representation of what the property will look like (I'm not painting a different color, doing new flooring, new landscape etc), then I start my ad a week or so before the tenant moves out.

They make powered ducts between rooms to cycle the air as an option if the rooms still need heat/ cooling.

I passed the Charles Barnes online program but I flunked my state exam with flying colors. :( I’ve been searching for PSI practice exams and heard about Exam Smart.

The house has no ducting or no attic so that is eliminated.

See the Zillow link for the property below; interior is only 2,000 sq. ft not 2,556 (2,556 includes the garage)https://www.zillow.com/homedetails/600-N-13th-Ave-...Work for this house would include turning it into a 3/3 while leaving the existing 2 car garage, 3 brand new bathrooms, remove the wall separating the kitchen from family room, refinish and/or replace kitchen cabinets (countertops will be reused), replace all exterior doors and windows with new impact glass, new HVAC system with duct work, minor electrical (high hats, new fixtures, inspection repairs), paint, new casing/baseboard, and maybe new interior doors. 

Sorry @Mindy Jensen   I am a w2 wage earner but I also  maintain my church 2 acres, bushes and flower beds for money for 22 weeks out of the year and put in some color during winter. 

Above it is a large arrangement of ducts that looks like a spider.

After you address the leak it might be worth looking at additional venting or conditioning the crawlspace with a duct from the air system.

If the lease prohibited painting the walls and they did not put it back to the original color you could keep the deposit to repaint the walls they mis-painted.
