More specifically, if I MOVE the stairs (we are talking about a 9-12 step straight up stair case), do I need to reinforce any walls?

-Sauna-Hot Tub-Patio/courtyard (large cement tiles on crushed bluestone with lighting, natural gas line to bbq)-Secondary patio off primary suite-Losing sq feet in the primary bedroom to enlarge the bathroom-High grade cabinets-Appliances with cabinet fronts-High end appliances (Viking/Miele instead of GE Cafe)-Outdoor shower (teak box walls with a dry well beneath the footprint)-Wiring for Cat6 to every room-Wiring for surround speakers (or including the speakers that are built into the walls)-Sonos whole-home audio system-Hardwired cameras (with on-site storage) to the exterior of the house-Smart features: thermostats are a given, but how about light fixtures, switches, aromatherapy, fans ... anything else?

Thus, the next challenge and frontier for many DSCR lenders seeking to serve the growing number of real estate investors pursuing this strategy is to cement a qualification and underwriting methodology to properly qualify MTRs and accurately project their revenues.

Your focal points are accessible/mouthable  surfaces such as window sills, handrails and frictions surfaces such as doors, windows or stairs.

You should be able to put them up on the exterior of the property in the public/common areas - parking lots, stair ways, and hallways.

But the hidden back end costs lurk in the installation fees for padding, stairs and overall install costs.

I recently made a post about my favorite house hacking strategy which is to find a house that has a basement entrance or one that has some sort of side or garage entrance that opens up to the basement stairs and turn that into a basement entrance.

You forgot getting the toilet , carry it up the stairs , assemble the toilet , fix the broken toilet flange , disassemble old toilet carry down the stairs , trip to the landfill .   

Appreciate the inputIt's a good way to finish bare treads on stairs.

We're going to tear out the drywall around the jacuzzi, replace it with cement board, add a shower head, and tile the surround.
