If you currently have a forced air furnace in the duplex, an a/c unit may not be too expensive, and probably won't require any additional duct work, assuming the furnace is relatively new and a compatible a/c unit is available. 

To get a taste I'd recommend acquiring a multi w/value-add (lots of sweat in other words) in a B+ area wher you can live and rehab and above all, LEARN as I've observed over he years it's not how much capital one has at their disposal but knowledge that will ultimately yield you the "cash-flow" you're aspired so to grow.  

Hi Darius, Yes, you could buy property B and then refinance the property to generate additional cash to complete the acquisition of Property A. 

P.S.S In addition to finding advisors.

I am looking to rehabilitate properties for rent in order to make a profit that can be turned back into the investing cycle for more properties or maintenance on properties already acquired.  

I would also like to connect with additional agents for any current opportunities in their respective territories.Thank you in advance

@Francisco Trejo I don't think an addition is anywhere near the complexity and cost of a new build.

Roof, exterior work, additions etc...

I currently have two duplexes in my portfolio so I'm aware of the inspections in that situation, but not sure what additional inspections I should have done.

Unfortunately, my current employment will not cover the additional properties but with the tenants' rent I could pay for all said expenses.
