Sometimes the "condition" question can be as simple as the home showing clean, good smells, bright light....

Start looking at things that need a light renovation to increase your monthly cashflow and equity. 

Also a lot of lighting.

I would say one of the biggest things I see problems with is guests coming in and clicking buttons right away.I think it is necessary to have laminated signs that tell guests how to use things like pool + spa remotes, A/C, specific lights if they are high tech (mood lights, color changing lights), and other things that a guest can get confused on and mad that it isn't working properly.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

I was going to paint the cabinets, add recessed lights and have the whole room plastered and repainted.

How are your numbers looking in light of the fact that prices are stagnant or falling in most markets? 

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

You will have to locate the area using a black light and once located you can then deal with the issue, if it is cat urine related.Absolutely charge them if they left the property smelling bad.  

Needs to be in writing (email etc.) but generally, we don't allow any changes until at least the 1st full year.After that, use your best judgement and go on a job-by-job basis and inspect (for example: they paint one wall or room before you let them paint multiple spaces, AND the color is approved in writing as well).
