One client looked at renovation loan, then just bought with 20% down, and after closing financed RTA cabinets, flooring, etc. on 2-year no interest loans, purchased custom windows direct from manufacturer, has licensed electrician and plumber helping him outside their job on weekends for much reduced rate, etc. 

I would upgrade a slummy looking kitchen or bath with builder grade materials or do tweaks to something old looking but in good condition (refinish a pink cast iron tub, use oil based paint to cover dated bath tile in good condition, paint good condition cabinets white and add new counters)

Anyway, agree that you have to sometimes replace subfloor- and definitely clean the venting system for HVac- and also any cabinets in the basement or anywhere else saturated leakage could go. 

Cabinets look like they are in good condition.

Most of it was a roof (almost $5k) and cabinets/counter ($3k) and that was hired out.

Ceiling fans are $100-200 each, cabinets are about the same depending on where you buy them.

To start, the numbers:3 bedroom, 1.5 bath 1700 sq foot brick SFH with bonus room.Purchase Price: $59kAppraisal: $105k as is with estimated $124k after rehab.Renovation budget: $20k.Renovations include: new flooring in bonus room, kitchen and baths. total renovation of bathrooms, new cabinets, crown molding (to cover bad drywall job by previous owner), buff hard woods, paint exterior, paint interior, remove awning, remove side door and seal up, fix low spot in kitchen floor, and remove the non-permitted fire place.Estimated Rent: Initially I budgeted $950 per month based on another rental I own in a similar location, but  two houses on the same block were recently rented for $1200+.

need help on painting walls on my new purchase home where I have old what trim and cabinet

It's a nice 3BR1BA house which needs no major repairs and could use cosmetic upgrades such as paint, flooring, landscaping, appliance and cabinet upgrades possibly (which I will all be doing myself while living there).

Could another cabinet of drawers fit in there?
