@Patrick J. in my experience, most negotiations revolve around three areas 1) roof 2) HVAC 3) health and safety.

According to the lease, the tenant pays a base rent plus estimated CAM charge each month.

RTA....ready to assemble, search on YouTubeTheir are various types, but, generally they don't differ too much...Usually their are a series of various types of predrilled holes for cam-locks, dowels and wood screws along with dado cuts for the base pieces and face framesAlso, good handyman that he didnt just start butchering them

HELOCs are also the only revolving debt that, if you believe the "what if" software, your % utilization does not matter.

What would you recommend to someone who is very passionate about a specific niche, but just does not know enough about it to fully commit to developing his/her personal brand revolving around that niche?

In Denver it’s easy to find people looking to rent but it’s also a transient place where people often move after 4-6 months when they find things don’t work out and move back where they came from, so with strangers you may end up with more of a revolving door than if you find friends who you know are planning to be there at least a year or two.

@Kirk Perecich, depending on where your rate is now on your 1st mortgage, you could look to refinance that (in hopes to reduce the rate), pay the balance down with the funds you have "just sitting in the bank making nothing" (depending on how large of a sum this is, may or may not make sense), and then open a HELOC to create an open/revolving facility to use for future investments. 

Do I need to approach the local City for any info that may help or does the resolution revolve around negotiations with private parties, such as the neighbor?

@Cam Vankerkhove that’s awesome!
