It is one thing to land a National account, quite another to get some guy that has set up a one man corporation with fast talk and nothing to back it up.

not sure what your trying to learn or do.. but just pay them by the door.IE  10k 20k 30 k 50k.. each GC will have their own fee.Myself I pay on the low end because i do all the accounting for the GC he only has to cordinate the subs .. 

It is also uploaded onto our PM software for accounting, systems, etc.4.

Open a business checking account, obtain a DUNS number, and look into setting up accounts with companies that report to business credit agencies (e.g., net 30 vendor accounts).

So if I wanted to build a 10K monthly income I would need to own 30 of these accounting for turnover and vacancies. 

Alternatively you can invest in better neighborhoods, perhaps be forced to leave some of your cash in the real estate but experience meaningful appreciation or if you choose to sell, be able to turn the forced appreciation into cash in your bank account.

I think that is just rage posting made to drive up interaction with that account. 

Those things would account for about 25% of the incoming rent or $525/month leaving you only $1575 left to pay the mortgage.

It feels like the city can operate without accountability.

I recommend you do this annually to adjust for utility increases and other variables.
