That sounds like a much more resonable refinance rate and would definitely increase my return (~64%)4.)

However according to the US Census Bureau in the City of Mishawaka, the owner to tenant ratio is approximately 50/50 here http://www.census.gov/quickfacts/table/PST045215/1...To also break down the numbers in one line, from the Census Bureau link, the City of Mishawaka has a population of 48,261, a total of 24,088 housing units (as of the year 2010) of which roughly 12,044 are rentals with a median gross rent of $714.00.So in summary, in my opinion, this is a strong rental area with stable economic fundamentals to sustain the tenant pool.

Just want to find a property that can sustain itself when I move out. 

I'm sure there's more to the quote but this is the part that resonates the most...sorry Brandon!  

Yes, the rent growth was more than 2% in the last 4 years but a) it's slowing down now and b) I think 4-5% rent growth this is not sustainable long term.

Challenges could include:Having the population to make it a sustainable day-to-day venture.Finding quality staff is tough these days, don't care what you pay them.Breakdowns/serviceInclement weatherPennies on the dollar at exit If the truck does say, 1000 bucks and after labor/cost of goods the operator's left with 500 - 600, then has commissary expenses and a possible split with a partner(s)Ehhhhh...burnout.There were dozens of trucks here 5 years ago and only a handful have really survived the grind. 

SAVE money so you will have a "grabstake" to begin investing withFrom the vantage point of my 40 years involved in real estate investing, I offer these conclusions.First, for almost everyone, a true education in business, investing and or real estate is required for sustainable long term success as a real estate investor.  

My goal is to develop beautiful, affordable, sustainable houses in B neighborhoods.  

I mean, there's a whole other side of it making sure you get a property that can sustain the numbers and there are different risk factor levels of course, but for what you're asking--it's all about the numbers.

Reason why this is important is because you want to make sure that rent is sustainable.
