My question is, should I pay-off my primary residence mortgage to 1)Get peace of mind and some sort of security 2)Opportunity to borrow from my equity if needed 3) Extra cashflow to save and invest in another rental property in the future OR should I keep my primary residence mortgage (due to the low interest rate) and purchase another rental property instead?

It’s a tactic that can work, especially when both parties understand and agree on the process. the issue is with this sub to  soup de jour your going to get all sorts of fraudsters coming to play and that is just a fact.. once they figure out the angles..

We have investors with all sorts of backgrounds at our meetup, and all love to talk about their strategies.

If you run through the worst case scenario, is it that bad? 

Worst case, I can look up zoning changes and match the address with recent sales, however, if no permits were pulled I do not know if renovations occurred further increasing the value.

Worst case - you have to evict them.Hope it helps - and all the best!!

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.PM us if you’d like to discuss this logical approach in greater detailP.S. we've ranked all of Detroit's 183 Neighborhoods, so you can make more informed investment decisions.

And it's a lot easier to sort floating that monthly interest payment then a near $500k total right. 

I don't know how long it can last though as it is the sort of channel that once to many people start doing the whole channel will become ineffective.

So they have to be placed & picked up quickly, or at the very worst cost so little that it doesn't matter at all if the authorities remove it.
