Something important to keep in mind is a lot of investors in Wilmington invest at a street level.

This way its not just a one way street.

They're everywhere - whether it's Redfin....or the Wall Street Journal.The info you want to hear and listen to is information coming from other investors working and profiting in your local area.

So, are there any entry doors not visible from the street? 

You can't run down the street to check on a house in Cinci. 

Below are some more details and a few questions.PROPERTY/LEASE-rural Minnesota town (around 5k people population)-built in 1974-property is in good condition, right on the main street-10 units ranging in sqft-1 unit on a 3 year lease, 7 are on a month-to-month lease (not sure how long they've all been there), and 2 are vacant (yearly rent for these 2 open units combined would be around $22,000)-there is room for about a 5% increase in fair market rent for the units on a month-to-month lease-the expenses paid by the owner are taxes, insurance, utilities, snow removal, cleaning the common areas and minimal maintenance-yearly rent $133,560-yearly NOI of $103,447QUESTIONS-what are people seeing for office/retail CAP rates?

Quote from @Sami Gren: As long as they retain possession, they are legal tenants and you can't change locks, throw their stuff on the street, etc.I would contact them and give them 48 hours to remove their items or threaten to put it in storage and hold it until they compensate you for the extra rent, utilities, moving, and storage costs.

A couple homes across the street with similar square footage are actually above the 500k range.

And current zoning is for single family and two family.5- all buildings and units are exactly the same. identical inside and outside6- this development will have four buildings, 8 units.7- 8- building duplexes and keeping them as long term rentals9- I live right down the road, and any work I’m not doing myself I manage remotely or on site10- I would say the area is A-/B+   Nice area, nice school district11- these towne homes are in an older, but still nice neighborhood, I wouldn’t say it’s gentrification, but just a cherry on top of an already nice neighborhood12- all utilities are underground, you can see in my IG feed, @awtreyrealestate, and I am the sole owner of all the lots and buildings so I basically am the HOA, responsible for streets and such 

If you're in town, make random drive by visits to see if everything looks good from the street.
