Are there other cities and states or multi units are more prevalent?

Back in the late 80's interest rates were high, tough to make cash flow, so we increased contributions $1,000 month, and with the small cash flow from the 2nd and 3rd properties, we cash flowed 3 years after we started at $1,300, which includes our contribution.Then by 1993, interest rates dropped from 13% prevalent in the mid 80's to 7.5% by 1993, and I refied everything.

But I haven't traveled widely so I honestly don't know how prevalent that is.It's worth a visit if you're able (google RIREIG); the first meeting is always free.

@Elliot Savin the situation is prevalent enough, a lot of the folks on BP making a living doing exactly what you are looking to do.

So, the cautionary tale here is that those vague weasel clauses that are prevalent throughout lender-favored loan documents can come back to bite you in a big way, especially when in the hands of a note holder blazing a new path that nobody else agrees with but they have the weasel-clause-endorsed right to do so.I will need to look hard into refinancing. 

Apparently some of the neighborhoods where multi family homes are prevalent have a higher crime rate so it was decided that forcing the properties with 3 or more units to remodel to 2 unit properties would somehow rectify the situation.

This crowd is prevalent on BP but can sometimes sound like your grandparents who, having lived through the Depression, never trusted banks again.Still, that doesn't mean they are aways wrong.  

And it's become way more prevalent in the last 2 years! 

As we start seeing STR restrictions in more areas, I wonder if MTR is going to become more prevalent?

Now I'm aware of the current lack of inventory that seems to be prevalent in the SFH market, especially here in Denver.
