I did a walk through on the property, and I think in my current market that this is not a reasonable choice for my investment money. 

what information or references would you need?

To kind of give you a sense of what you are asking, it is like me asking you if Eating Out is a good choice? 

The choice between maintaining liquidity versus reducing debt will largely depend on your priorities and future investment plans.As for subdividing or CPRing the property, there are several advantages.

Congratulations.Tough decision.I think you really have no choice but to sod at least the front.Don't use fake turf, and it isn't cheap anyway. 

In return my tenants treat me and my properties very well, stay longer and refer friends.  

Since you are focusing on 30+ days walk into the lobby of an extended stay hotel (Homewood Sweets, Extended Stay America, Choice Hotels with Extended stay etc.) and look for the reader boards.

Going to make this into its own post for others to reference in future!

- How long the unit sits vacant for repairs/cleaning, and finding a tenant- City/town/state the unit is inPlease respond with your thoughts, hopefully with the bullet points above as points of reference and stated as such in your reply (I know, I am asking for a lot from you all :) ) But, for example, a Class D property in Milwaukee, WI probably requires less turnover time, lower quality materials, not as precise of a paint job, etc, than perhaps a Class A property in San Francisco, which would require higher quality materials, higher labor costs, longer vacancy since more precise craftsmanship would be required, etc.

Beyond the formal checklists: no evictions, 3-4x income to rent, prior landlord references, employment checks; I would also look at things like responsiveness to communication when we are setting showing, were they on time to showing, did they look me in the eye and shake my hand, did they show up to showing high?
