I also assume total rehab to be $3000, thinking that I might need to buy dishwasher, refrigerator, washing and dryer machine for both units (one for myself and one for the rental unit).The rental rate for the other unit is assumed to be $1000/month.

Although I did not take @Julie Kern's full advice on reducing the rehab, I did reduce our scope of work a lot so that hopefully we do not overdo it.Scope:New flooring - laminate downstairs, carpet upstairsNew kitchens & bathrooms - complete gutsNew RoofElectrical work to remove wallNew Privacy FenceSmall things I plan on doing myself:LandscapingPaintWhite wash fireplaceOne thing that is giving me anxiety is the house has those stupid textured ceilings :)  that are harder to get off than normal popcorn ceilings.
