Hardwood floors are pretty durable . 

They are allowable per code here but are generally looked at as temporary solutions and to be honest you can get a ring crimper for the price of about 4 or 5 press on fittings... thus cheaper and more durable/leak free to go the crimp ring route..

Balancing aesthetic appeal with durability and cost-efficiency is key in this process. 

Buy, refinish the floor, spiff up but don't modernize, then trot on down to the Huntington Collection and furnish with quality, durable antiques.The niche market I'd target is rich parents of out of state child actors coming out for auditions.

I recommend addressing soft spots in the floor by replacing the subflooring, rather than covering them with new flooring, as it ensures long-term durability.

I agree with starting with durable construction, durable furnishings, etc.

This will be much more durable and stand up to water a lot better than vinyl.

And the ability to continue to harvest depreciation over the years with an extremely durable asset is key.Last thing that didn't get mentioned specifically I don't think is the "tide effect" of inflation. 

If you flip to rent you will go more durable on finishings than you would to sell so you want to decide on that, but when you are done, you can see where you are at for sale vs. rent and decide, you would just have to move to traditional loan to carry it if you rent.

I'll be ready to purchase another turnkey Sept 15 and I really hope these homes are rehabbed well, because durability is my number one criteria.
