Are you saying that businesses would prefer their rent to stay a flat rate for 3 (+/-) years and then have it increase x% as opposed to an annual increase?

There are mid-size brokerage firms that do great training and offer compensation split somewhere between the KW/L&F and the flat-fee brokerage co.

I was wondering if I would pay broker a flat fee instead of per transaction

Right now he is flat out telling you he may not be able to afford your unit.  

I was able to convince my wife (a lot of work) last year to buy a three flat instead of a single family home and we are both very glad we did.

We also use only large flat sheets and tuck the bottom sheet (that therefore can fit any size bed) so instead of full fitted/full flat/queen fitted/queen flat/king fitted/king flat we just have one sheet to deal with.  

A good way to check if they are still in the property is by placing small aluminum 8x9 baking pans with water and dish soap on the floor, spread them through out the rooms.

*the flat fee for the LOC is 5k and there is a processing fee of 2k*lets say I pull out all the funds available just in case I need to cover an expense I did not see coming and the monthly payment, total repayment is 157k*then i sale the property for 210k minus the total amount invested 157k profits is 53k.This is how i understand the LOC process and pay back.

I'm still learning, but I think my meat and potatoes will be investing in 6 flats.
