I believe I can provide neutral, third party analysis if needed.

It sound like you either have a property in a sub optimal location, paid too much, or need better management of the building.In my opinion, if the problem is either of the first 2-selling at neutral, all costs considered, is a victory.If the 3rd-then new management is called for before selling the building.I wish you well

Use one neutral color for the whole house.

@Mandi Martinez, while it may be true that it is often safer to go with neutral color schemes on a flip, you only need ONE buyer that likes the color you chose.

I also would not entertain a tenant wanting to paint a unit /have it painted anything more than my standard neutral color that I use on all my units.What you are trying to avoid is (a) a tenant dictating the color of your paint, only to move out 3 months later, (b) a tenant asking for and being granted an "improvement"; this sets expectations moving forward, (c) any cost to you for any of this stuff.If a tenant wanted a unit REPAINTED (it would be my standard color), I would calculate the cost of materials/labor, do the math and notify the tenant that you would be happy to paint their unit, but it will cost "$x" which would require a rental increase of "$y". 

@Billy SmithThe real million dollar question is will RE prices go up or down after Covid 19.Or shall we buy, or sell,, or stay neutral?

Survey the house and take care of the easy fixes including:Fix all loose tiles in the bathroom or kitchen.Fix all loose hinges on doors or cabinets.Unclog or replace stuck drawer tracks.Repair any leaky faucets and ensure all plumbing systems work.Remove carpet stains or refinish hardwood floors.Depending on how much time and money you want to spend getting the home ready, you might also want to update fixtures, buy new appliances, install new hardware on the cabinets, and give the interior a fresh coat of (neutral) paint.

Let's suppose the borrower was willing to put that $60k into some escrow or neutral 3rd party account somewhere instead of using it for rehab, and is willing to sign an agreement stating that if they ever default on any mortgages that you gave them, you get to keep that $60k, and as soon as they have paid back any/all mortgages to you, they get their $60k back.

I personally would choose a neutral color (Kakhi/Grey etc) but bold color statements can work in the right area with the right setting.

It would make the purchase net neutral and the lights would be under manufacturer's warranty for the entire term of the financing and beyond.
