Rather it's about the property growth prospects.For instance, if you find a property where the rents are $200/month below comps because the units have 1970's decor in an area of high rent growth and the owner is an older retiring individual you may have something even if the current numbers don't work. 

We then approached the bank to refinance, and the appraiser (I think partly due to my wife's keen eye for decorating) valued the home at $215,000. 

The tenants will use a card to pay, the third party will collect the payments and payout 50% of the gross income to the landlord.There third party will pay landlord $250 in decorating costs and require landlord to make the laundry room accessible to tenants between the hours 0700-2200. 

Another option would be to contact local interior decorators.  

HD carries their own line of cabinets called Home Decorators Collection.

Then go to a home goods store and charge about $1000 of staging decorations—pillows, Knick-knacks, fake flowers and plants, throw blankets.

I am going to turn one of my units into a vacation rental. I would like some assistance from a professional, or someone who knows what they are doing to help guide me in making sure the unit flows nicely for a vacatio...

If you’re wanting to be the project manager yourself, I have had a lot of luck in calling specific wholesalers in the area you’re looking at to get 3 recommendations (Sherwin Williams for paint, Floor and Decor for tile, etc).

@Jennifer Marshall floor n decore in Austin has 12x24 black granite tile $8 EA as well as precut granite counters for 3-500$.
