If someone has a low score because they've had problems with cable/cell phone companies, gym memberships, medical expenses etc. but have always paid rents I'd consider them.

I invest in merchandise I can find locally (camera/filming equipment, IT equipment, inventory liquidations, video games, audio equipment etc.) purchasing from auctions and locals looking to sell and then sell the merchandise on my eBay or Amazon store.

That's a recipe for problems down the road because unexpected expenses (i.e. car repair, medical bills, etc) always seem to come up for many tenants.

My wife is medical field and I am business for self so i really don't need the right offs.

I saw on another post where the seller just wanted to pay off some medical bills, so they worked about a payment plan and the buyer paid it down (seller gave credit toward down payment at closing I presume).

I'm not a researcher and am not involved in the medical profession.

Not only have I been to Yacolt, I did an inservice with the North Country Emergency Medical Service there, teaching how to communicate with patients who are Deaf and those who use languages other than English.

I also like medical center area but don't own anything there.

We tend to ignore medical and educational debt / black marks but our flags are raised when we see cc missed payments, cable, power, etc. 

If you are considering it for an alternative to a 401k there was also mention on one of the podcasts or blog posts of using HSA medical account contributions which can grow tax free for medical expenses later in life when these costs will be higher, downside might be that the companies you have them with might not offer many investment options so the return might not be as good as your options in a standard investment account even taking the taxes into consideration.
