There are a lot of resources here at your disposal. 

Purchase price: $279,000 Cash invested: $45,000 Sale price: $425,000 Off-market property I found, contacted the sellers and proposed a cash offer of $279K "as is" (suggesting we would clean out the entire property & dispose of whatever the sellers didn't want.).

I'd also install 1) can lights in the kitchen, 2) under cabinet strip lighting, and 3) a push-button for the garbage disposal.

First, if you have access to equity relationships who only expect an 8% cash on cash return that is extremely inexpensive equity you have at your disposal.

Zoning make sure its zoned  then health department for waste disposal.

@Mario MoralesSelling directly is the cheapest route of the two you list - but realize that one (the refinance) lets you keep the property and the other disposes of it. 

In Subto we have a "Zoom vault" and man - its a gold mine - just search for something & its there with tons of videos at your disposal.

That one person will have many different options and banks at his disposal.

You'll also have a court order in place that will prevent the tenant from suing you down the road claiming you disposed of something of value. 

Kitchen will have all amenities including dishwasher, fridge, oven, garbage disposal, walk-in pantry with microwave, eat-in island, etc.
