Quote from @Ryan Duphorn: It depends.

A lot depends on your particular situation.

Short answer is yes but the correct structuring may depend if the properties are leveraged or not. 

Those are people that don't have anything at stake in your situation and they most likely don't have experience in that specific market area and those statements depend on your time frame and are market and property specific.Now, here are 2 specific examples of properties that I owned that I would've been happy never owning.

To answer two of your questions:  - You can register your LLC(s) in one state and invest in another, but how you do this will change depending upon where and what your investments are.   

There are some companies that will lie to you just to close a sale and others that will be honest knowing that individual buying parameters vary among investors. 

Depending on the area of town this doesn't matter much. 

I am looking to buy properties to rent out preferably multifamilies, or even a flip depending on the numbers. 

Hey Amanda, If these are residential properties, then you have 2 options for refinancing - 1) Conventional - Takes your income + debt and thats how you qualify. 2) DSCR: Takes the monthly rent - payment and thats how you qualify, pretty simple.If these are commercial, then you will have different options as it depends on the type of asset they are and cashflow. 

And the income approach is not typically reliable, since 2-4 unit property rents typically vary widely, depending on many factors, and the grm's (gross rent multipliers) will reflect that, therefore, causing a wide range in values.
