Average length of tenancy for multi-family is three years (I read that somewhere), but the tenants at our multi-family tend to stay in place longer.

Development projects here in Houston are generally 1 year in length for the simplest ones just to get through city permitting then construction, as I'm sure you're well aware.

As has been discussed at great lengths in this forum. the only ones who tend to defend the property managers are property managers who post here

Kristine Marie Poe  was so careful to document rent comps, and stay at arm's length in the compiling of them, when she was writing above.For example, if you jacked up your tenant's rent from $3K to $15K/mo to ensure they would leave, there is an argument that your true intent was to evict the tenant, but because you did not have "just cause" you did it anyway through a different means.

I couldn't read your whole post due to the length,  But the 16 year should be legally capable to watch the other kids and I believe that's the Moms call.

I would be sure to speak at great length to @Andrew Syrios who owns and manages a lot of single family in the urban core of Kansas City and to @Jan Pauley  and to @Chris Lengquist and @Chris Dawson and @JJ Pawlowski as they all know the ins and outs of the Kansas City Urban Core Markets.The Kansas City urban core is a great place to make money if you know what you are doing, I have been in real estate for 15 years and we had 50 urban core Kansas City Houses and we sort of knew what we were doing, we did our homework, we were hands on and lost our shirts.  

For example current job and length of employment, spouse current job and length of employment. tax returns for two years, Banking history, most of the time they would like to see 3 months of all active bank accounts, and your credit score.

And even at 1 Million, you would want to buy it with all cash to get a return, otherwise you are waiting until the mortgage is paid off to get any return, and over the years be it 15 or 30 year mortgage, you will have capital expenses like new roof, kitchens, bathrooms, etc. which will push out the length of time before you make money.I hope we get some more comments from people near your market. 

Mortgage terms in Canada do not run the length of the amortization as is common with residential financing in the U.S.A..  

In return you will get continual work from me for the length of my career, (which will be for at least the next twenty years!)
