The hardwood floors definitely need refinishing and a fresh coat of paint especially on the exterior will definitely go far. 

You could do the time consuming and painstaking tasks like filling in the holes left by finishing nails or sanding drywall between mud coats.

Some Kilz odor blocking primer, a coat of paint and LVP throughout.  100k profit!

The "White Coat Invester" holds a strong bias against life insurance.

The chipping lead paint on my garage can be easily fixed by just vinyl siding over the paint or scaping the flaking paint off and applying a new coat.  

It looks dingy and needs to be "Turned".If it were mine, I'd do the turn and 100% repair everything, such as the back door allowing light through at the edges, the squeaking floor, etc... and there is not much kitchen counter space....Class-C's like to cook at home....perhaps extend the counter over to the stove, and maybe put in a bigger fridge, and a bright daylighter bulb in the kitchen.Also the living room floor looks wavy...I'd have that fixed, and remove the big brown shelf or put it in the laundry room over where the appliances go and paint it the color of the walls (but vinyl coated metal mesh shelving works better up there in a rental).That plus some (light) grey paint and "Properly installed" (non wavy) carpet.And look for Forever renter types...for a 1 br/1 (spacious) bath.Know your demographic, and know what they want.

And, please put on your coat of armor for just a moment:  the problem here is your lack of knowledge of construction and construction management. 

@Kathryn SchauerThere are many products that can be used as moisture barriers; non-permeable coating like SealKrete, rubber barrier product like a house wrap, etc.

If it went to the subfloor - mop with bleach mixture, let dry; roll on two coats of Kilz and one coat of clear sealer. 

For most of the homes the carpets alone were $3200 to $4900 plus two coats of paint on every wall and ceiling, replacing broken bathroom sinks, kitchen sinks, faucets, repairing air conditioners, replacing cracked times on roof 36 feet high, bringing in 4 to 8 tons of rocks to make the yards look nice, trimming trees, repairing sprinkler systems and the piping, replacing refrigerators, stoves, washing machines clothes dryers, water heaters, painting garage floors ceilings and walls, bringing in 20-yard trash bins to remove all the carpets, trees trimmings and trash left by tenants, replacing all the window blinds, door knobs that are broken and locks for the main door and locks for the garage door so the keys match, repairing garage door openers that are broke, repairing the garage door rollers and seals, painting the trim outside the house, replacing facia boards that are 36 feet high, replacing window screens and the screens on sliding doors, replacing entire windows just because tenants broke the window locks and they cannot be repaired, replacing kitchen counter tops that are destroyed, replacing all the kitchen doors and drawers because tenants destroyer the cabinets by hanging their wet laundry in the kitchen cabinet doors to dry. replacing garbage disposers, dishwashers and the list goes on and on.
