Add extra exterior lighting.

It needs a new breaker box and light fixtures installed in about 3 bedrooms.

I'd tell them that's because the guy was coming every week, since I couldn't guarantee him a weekly job I had to haul my mower over, which costs $50.Changing a burnt out light bulb-$10.

The bathrooms need toilets, tubs, lights & vanities; the kitchen needs cabinets, countertops and appliances.

I've yet to meet someone who has a strong foundation in financial modeling who will take assumptions lightly.

Basically a large hole in the ground to contain the water so that is drains out slowly under ground via a drainage field, rather than sitting on top of the ground making mud.Another option might be a cistern to gather and use the rainwater in your house, rather than city water.You would have to take steps to keep it free of mosquitoes and debris, and filter it going in and maybe coming into your house for drinking (ultraviolet light system).

For instance on a HUD house: "HUD-9548, Sales Contract, dated 1/99, contains a warning to anyone who makes a false statement that he or she may be subject to a fine not to exceed $250,000 and/or a prison sentence of not more than two years"

I think you should just stick with neutral/light colors like beige, baby blue and off-white.

You can see the lights go on when you explain why they arent getting ahead finacially and why they have trouble with customers.

I think the OP should at least warn others about how the experienced developer operates.
