I would look into a DSCR loan option it will require 15-25% down depending on the lender but it's based off the asset and if it debt services rather than based off the individual. 

It depends on what you're trying to accomplish... if you're not planning on investing in properties here, or even using the license part/full time to broker transactions - then I think you answered your own question. 

I have 2 dependents and will be the primary caregiver for both my parents and his parents as they age so we want to hustle now so we aren't stressed financially by these responsibilities in 10-15years and are able to maintain the standard of living we have achieved with income from our (now) primary business. 

Of course, there is a fee for this, $250 and up, depending on the size of the dwelling. 

They add that to your w-2 income and out they spit how much you owe on taxes or how much you get back depending. 

I think it depends on your goals and what you want to get out of it.

The long-term capital gains tax rates are 0 percent, 15 percent and 20 percent, depending on your income and status (single, married, etc).  

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

If you are targeting these areas with a roommate for a 2 bed, your share will be $3.5k / 2 = $1.75k  or $1.16k if there's 3 of you per month in rent give or take depending on your agreement. 

That sounds like capital gains tax on $63k-$113k depending on sales price and closing costs.
