What cities are you primarily focusing on. Looks

So I've made a decent return on the appreciation, but it seems that at this point, the money could be better invested elsewhere.With everything that's going on in the market, where would you focus on looking for deals?

I would hold off on looking for your next deal at least until you have enough signed leases to cover the mortgage; I've found it takes a couple months to get tenants placed and get rents coming in consistent enough that I consider a property self-sufficient.

(Worry #6, anyone who actually visited the property would see neatly trimmed grass and plants, snow was shoveled, trash can has recent trash, there are cars with clean windows and obviously used regularly, there are cats in the windows, lights are on, looking through a window shows furniture, etc.

J is spot on. Look

There are some rules about how many fixtures you can put on a single cable, but as I understand it, your "about 64" fixtures mean you can probably run two or three cables and be OK.If the lights are just "dumb" - they just light up when you apply +12 V, and you want individual control, then yeah, you'll have to run one cable to each fixture from some common location.Good call on looking for a good power supply. 

Our contractor suggested that the bricks could be sealed (maybe), but on looking at the photos said these are too far gone to seal. 

Congrats on looking at your 2nd property!  

We weren't able to do that with this fairly new build but we plan on looking for our next property in a  few months after we're settled into this one and built a "system" around it.  

In a case like this its much easier to come up with a solution if you can actually see what's going on. Look
