Would a bridge loan allow the sale of the newly purchased home instead of my existing home?

A hard money loan with 10-15% down may also allow you to keep the Atlanta property, if you have the reserves to do it.

if you are getting just started, i would just use your personal name and get the freddie/fannie 30 yr fixed loans. gives you way better cashflows up front which allows you to grow faster in the beginning. 

You could get the DSCR on first and if your bank allows it do a second position HELOC on the investment property (this would be pretty rare if a bank allows this) but putting DSCR on second would not be ideal.

Personally I like leverage, it has allowed me to recycle my money and scale quickly.

I have talked to my HML for the property owner to do a 24-36 month Owner Finance for the 20% down to allow me to qualify for a DSCR on a turnkey small multi-family.

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

Allow a pets and I think you will have a great spot.Would adding that extra space/ spending that money be reflected in an appropriate increase in the property value too?

Hey @Tarcizio Goncalves, QuickBooks Online allows for everything you need. 

While residential development is generally restricted in these areas, there are specific circumstances under which it may be permitted:Special Mixed-Use Districts (MX): In certain M1-2 zones, residential use is allowed when paired with a residential district under the MX designation.
