What markets have you looked into specifically to purchase more property in? 

One of them told me that if I close the loan directly into an LLC (which he confirmed they can do), then it won't affect my personal DTI ratio when I'm looking to qualify for future loans, specifically my next primary/house hack that I plan to buy at the end of next summer. 

Find a specific niche that you are interested in, find a mentor and then educate yourself.  

And we have a separate LLC per investment property, incase we get sued, they can only sue that specific property - rather than me personally or any of my other properties. * Should I change what kind of mortgage I have since it is technically no longer my primary residence?

But we would like to narrow down to a specific area if possible.

Not to get political, but it's very interesting to see what it's doing in specific areas. 

I was looking for anything specific or recommended.

All in all rates for MF investments range between 7.000% - 8.000% in this specific scenario.

I truly can't give you specific answers that you're looking for.

What I often see being a mistake is people ordering a cost segregation study before speaking with their accountant to see if it would benefit them on their return.What a cost segregation study does is analyze a property further to identify assets that be classified with a shorter asset life than 27.5 or 39 years.The issue when getting an 'estimate' from a cost segregation study company is that they are not accountants(more specifically not your accountant).
