Maybe put some of that into a money market account or the stock market, so if an HVAC does go out in 2 months you can pull out $4-8k to replace it (depending on size, location, etc). 

The brands I've been bid on have been:Eco WindowsCGI Sparta SeriesLawson IndustriesESWindowsAssuraAssura is from home depot, main advantage i've found is that they have a quick lead time of 4 weeks, compared to everyone else saying 6-8 weeks.CGI I heard its a reputable brand with a good warranty Lawson, cheapest quote but Im' hearing has a huge lead time now and they have been messing up peoples orders with sizes or specificationsES Windows, comes from Colombia and I heard spare parts, replacements and customer service is terribleEco, I haven't really heard much about but price seems close to what I'm being quoted for CGI Spartas Anybody on here with more experience that can help me narrow it down? 

The easiest way to increase your bottom line with a residential rental property in any city of minimum size is rent it out fully furnished.  

Customer service is off the charts amazing4.

Depending on the size of your portfolio, I suggest considering either "PROPERTYWARE" or "INNAGO":Propertyware is ideal for larger portfolios, offering customizable and automated reporting features.Innago has been very effective for me, enabling property marketing, conducting screenings, and managing rent and maintenance requests.

Yes, for every data-based analysis in real estate, you need a large enough statistical sample size.

@Jason Rowlett If you are in city limits, I would call 311, and ask about building codes and minimum housing size.

For a building that size I would expect they would have had someone like a John Burns or someone else provide a report to understand the comps and current absorption rates and vacancy rates for this class of building.Now that you have invested, it cannot hurt to go out and view the property but what are you trying to accomplish by visiting ? 

My recommendation is to choose a medium sized management company, if it's one of your only properties. 

For properties that size I'm not sure cap rates will give the best story, but for the sake of answering the question, cap rates are a level of desirability in that sub market.
