For a 6 unit range in FL, you are probably not into agency financing. 

We're not going to do any showings (we've put up a lot of pictures so people can see what the room looks like), and we have a comprehensive application form to vet tenants. 

There's some places where there's properties in that range, but they might be tough neighborhoods or require a hefty rehab (or both)

Comps have been in the $140k-$150k range so I like to think I created about $20k in equity.

What price range are your target properties in?

Until you get to VERY large (near $1mm range) your credit score is likely to be pulled for each deal, commercial or not. 

I've had my current job for 2 1/2 yrs making 75K per year and have a clean background but before I had my current job I was unemployed for a while and ended up filing for bankruptcy causing my credit to take a huge nose dive (sub 500 range). my Question is: to avoid the credit requirement (I wouldn't be able to find a co-signer) would I be able to put an entire lease down as a security deposit and pay my rent as usual so long as my income qualified?

I’m interested in multi family in the $1-1.5m range.

From several contractors I've asked, I'm getting a  pretty wide range of pricing per sq. ft. for comparable builds.

I've noticed zillow buying up a few homes in the mid range category, which is around 200-350k in the midwest.
