Im noticing investors are very different and each have different criteria for what they are looking for in a flip.

Quote from @Ryan Fox: @Trent Davis- I bought the property last December and didn't notice any foundation issues at the time. 

I notice you skip right over who does the clean up, Jim, and who has to approve building in areas that aren’t defensible.I also see that now you admit that your fairy-dust belief that people “will” work with insurance companies to clean up is not necessarily true.

I've been looking in deal finder for properties and noticed to multi families aren't showing up in map view, but when I search them by address the listing appears.

I am looking to buy another multi family property but have noticed lots of obstacles when looking off market.

If you look at @Michael Plaks article you'll notice that the distribution isn't taxable. ...

What are some pro & cons you noticed throughout your endeavor?

Are you noticing specific property types, neighborhoods, or price points where buyers are finding the most opportunities?

As per the HSTPA, any changes to a tenant's lease whom have been in place for over 2 years requires a minimum of 90 days notice, regardless of what the lease (or lack thereof) says.  

Just keep the amount within any local rules and give proper notice.
