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. 

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).  

Meaning your 10k could at a maximum get you a $200k building, which may not be feasible depending on where you live.

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

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. 

Second, general maintenance and repair costs depend on the condition of the house, the age of the house, and who is hired to do the work.  

It depends.

(BP will be the new brand- 10 year lease with BP)Store was heavily dependent on game machine revenue which is 45% in state.

Also depends who you intend to rent to and the pet policy.
