As others noted, there is no limit to DSCR funding other than your ability to produce enough liquidity for down payments, closing costs, and the required reserves post-closing.

A friend of mine and her husband are working on a deal to combine an event venue and it will double as a film studio because they help produce a lot of films in Georgia.

There is some but you FB or local event would produce more.

I was told initially that commercial deals(5 plus units) were based more off income property is producing than personal credit/finances but that's not entirely true.

If you only have one LLC and don’t need entity tracking, you could get a lower subscription and categorize your properties as ‘customers’, then units and tenants would be sub-customers.Simple Start would allow you to invoice your tenants (if desired through QBO) and produce basic reports. 

And then finally, there is always the option to just claim the regular standard mileage deduction rate of $0.67/mile. 

How do other regular condos perform versus them? 

I fire clients regularly. 

Excluding the periods of “tulip bulb” irrational exuberance, a property must produce enough of a risk adjusted return to satisfy both the ROI demands of the “limited partners”, and the income/time requirements of the sponsor.  

And that's not even taking into account the regular tenant BS.
