To acquire more properties?

My property is on all platforms with Evolve. 

A 4plex isn’t a commercial property.

Can the property be legally rented long term (over 30 days)?

I would sell, pat yourself on the back for making good equity, and turn 1 property into 2.

the other rental property that is also under my name. 

Readers are advised to seek professional advice If you have more than one property rehab going on at the same time, how does irs/lender/investor know which expense goes with what property?

Every property you own is an investment so your journey has already begun.

My example was to compare and contrast, in general, that you will not find similar terms to what you find for US properties. 

I’m not only working on my case with these buyers and a DeKalb Pastor & Chaplain of DeKalb Sherriff Office on over 2.5M...but this now appears to be related to a HUGE Mortgage Fraud Criminal Ring here in Metro Atlanta with quite a few of confirmed fraudulent documents on many properties as more evidence shows up.Some of the names I have confirmed provided or created fraudulent bank statement, operating agreements and forged QCD docs to obtain mortgages illegally then allow them to foreclose.
