In 2023-24 there is market equilibrium or saturation depending on the market. 

Whether I refinance or not will depend on whether the property still cashflows.

Also depends on your school of thought. 

Depending on the reason you are noticing, time periods may vary as well.  

It really depends - sometimes with foreclosures, the owners are so upset they're losing their home, they will start destroying it.

Depends on the neighborhood and the property-type.

I won't be providing appliances but I know that for the section 8 inspection, part of that includes inspecting a working refrigerator and range.When I did Section 8 a couple of times years ago, I was sure the houses would pass or only need minor fixes depending on the inspector that I got, but I let the tenant move in right before the inspection so that their refrigerator and range could already be in place and be inspected.  

a lot depends on frontage, etc. best advice is to go to the city or zoning department yourself where it all happens.

It depends on how bad.

It may depend on market, but all of our travel nurses found us on Airbnb and Furnished Finder.
