)  Arizona Arizona is a snow bird state, we have golf, baseball training, then a dead hot summer where nobody comeshow can I come up with some numbers before wasting time to look for furnitures and buying beds ?

Buying a new one, changing tactics to LTRs, etc etc.

Then hire a handyman to put everything together.Rooms to go sells whole rooms full of furniture, sometimes at zero interest.

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Looking for suggestions on any specific building materials, fixtures, accessories, furniture, and tech for a STR.  

Our property was already functioning as a short term rental so it is furnished but they are getting rid of some of our furniture and putting in new furniture and they are just charging me for the removal of my items.

If you can get all the bedbug containing furniture out of the place and it will sit for awhile (or let it sit while the other repairs are done) you may be able to avoid some cost, but if you want to get a paying tenant in sooner rather than later you will want to bite the bullet and get it well done.

Make an insurance claim and buy all new stuff.
