Do you know how many times I've rented to someone that qualified, only to find they snuck in their drug dealing lover or sex offender brother?

Hey @Cam Clinger, I don't know about what the process for Tennessee is but I used Online Ed and they were great. 

VacantAll NNN lease with expenses reimbursement from the tenants. seems like a good location as it is just off of freeway and there is Chuck E Cheese, Apple Bees, Raising canes and other  good retail around the location.We are trying to get the latest income statements from the realtor to assess if the tenants are doing good (mainly from the bar which is occupying 50% of the space and lease coming to an end in 2022)According to our calculation cash-on-cash is around - 8.5% if the building is 100% occupied Assumptions: 25% down payment and 75% loan from the bank @4% interest rate 30year amortization Operating expenses included - Property taxes, Insurance, CAM, Management fee.Are we missing anything from the calculation ?

I have a certain ratio per100 headcount (not households, not age, not sex) I use when decidingto buy or build in a town.

Listing noted both units are rented month to month at $1,350/mo each, which was on the lower end of the market.What I liked: (i) Location (nice B+ suburban area, close to the Villages and Orlando, 65%-35% own to rent ratio; that particular pocket had low to no crime and no registered sex offenders vs. other parts of town), (ii) Product type (3B/2B duplex with a garage, which is rare to find and is ideal for both a small family or a single professional with or without roommates; most duplexes on the market have no garage at all and are 1B/1B, 2B/1B, or 2B/2B), (iii) Age (2006, i.e. while it was on the higher end of my age spectrum it was less than 20 yrs old), and (iv) Upside potential - opportunity to bring rents closer to market post close (tenants were on month to month leases) and forced appreciation by performing minor refresh with some deferred maintenance expected due to age (roof, HVAC, heater).

b) What type of systems are allowed (meters, RUBs or CAMs)?

If they have loud sex, particularly during the day, then I would try to document whether the sex is occurring with different visitors, record the cars and sex audio, then report it to the police.You can't control the neighbors.

Most residents would be very upset if they found out their neighbor was a sex offender or drug dealer.  

You could use something like trail cams.

Also I see what looks like a macerator on the sewage line with an electrical connection (to the right of the window).That might be in indication of sewage issues in the line to the street.You might want to have a sewer cam done (by a reputable company).Maybe try to find out the age of the macerator, and any history if issues, and if it truly is a home use macerator vs one for an RV.A home inspection might also be a good move.Also the old cast iron sewer pipe looks to be wrapped with some kind of insulation, you might want to see if you can get any info on pipes freezing in the winter for that building (or if the pipe is cracked and someone tried to bind it back together).Good Luck!
