If the current ones can be sanded down and refinished I think that would be great as long as you can get several coats of poly on there to really make them shine.

The property is in decent shape structurally, I will be putting another layer of shingles over the roof (one layer currently about to end of life span), Exterior needs a fresh coat of paint also.

We have rented our home so quickly between renters, we rarely have the time to slap on another coat of paint.  

Do another coat.

The Rule of Thumb - in the very old days was - used to mean that it was legal to beat your wife with a rod, so long as that rod were no thicker than the husband's thumb.The Rule is not intended to be strictly accurate or reliable for every situation!

Did they simply clean the carpet and give it a coat of new paint, or did they actually put in the work to give the prop a new roof, new HVAC, new flooring, etc?

If the unit is a rental and you don't want to spend the money to refinish the floors, sometimes you can get away with a buff and coat, depending on if any other contaminants have been sitting on the finish, such as floors being previously waxed or furniture polish that has remained on the floor when the previous owners were cleaning their furniture.

I gave my $300,000 move-in ready beautiful vacant home to this large well known local co in Oct 2016.( Ive owned and self-managed another very similar rental in the same subdivision-- since 1998--and it has never had one day of vacancy in 16 years-- rented at $1860.)This professional pm co put all utilities in their name on my new property and turned the hot water heater ON and the Water ON ( even tho the main water cutoff valve is easily accessible in the coat closet beside the garage, the entire 3 months they 'managed it').They let the property sit VACANT OCT-NOVand on their "routine inspection on Dec 1, to make sure hobos had not moved in" they SAW the water heater in the garage was spewing (at full blast) A 20' stream/ fountain of HOT WATERand that the entire finished closed garage was covered COVERED !!

Good evening,Get in touch with Jeff Coates (email me for the number, or look up online).

Other tactics I've seen used by other owners is coating it.
