Historically, interests rates and housing prices follow an inverse pattern.

There are some skills that I suggest every homeowner learns in order to avoid high repair bills (in order I usually do them):-Fix minor roof leaks & repair siding/exterior-Fix water supply leaks with compression fittings or hose clamps if needed-Install lights, replace bad receptacles, switches, or breakers-Install electric water heater if needed-Fix subfloor & sturdy up framing if needed-Fix/replace windows/doors/glass and install locks-Drywall/mud, brush&roll paint-Install floor (floating/tile) and cut/install trim-Install toilets/sinks/cabinets/faucets-install mini split units if no functioning ductwork

Meaning things like tile shower or fiberglass shower, vinyl floor or tile floor.  

I'll add that I once tried to use an epoxy kit to paint shower tile that was a dated.

I could have put a bandaid on as it still worked but I pride my houses in being higher end and good quality.As we continued with the house, I ended up putting in over the top finishes such as heated tile floors in the master bath and sound insulation under the hardwood floors to reduce noise transmission to basement.

A simple reface with tile from the mantle down will be less exp and will give the buyer more options.

You can also put granite over existing counter by removing tiles etc and paint it over. 

It also has a tile version which we will use for the laundry room of the flip.This is the laminate.https://www.lumberliquidators.com/ll/c/Boardwalk-O...The question is: should I use the same laminate in the two unit rental?

The closer we can get to the raw data, the better we can identify patterns, but Zillow, Trulia, Redfin, Homesnap, etc. all provide data.

Work I did myself: Installed new ceramic tile in the kitchen, basement, and bathrooms; painted; installed new kitchen appliances; installed new garage door; installed new screen door; updated landscaping; replaced water heater; updated bathrooms; added kitchen cabinets.
