I mean I used to work as a licensed contractor and for an estimate I would charge $47.00 per half hour of my time , still quite affordable if you ask me Plus that would put me first in line to contract with the cash buyer.

I charge the buyer let's say a 5k down payment to get in the house plus I profit off the difference in mortgage/rent rate right.

I've seen them charge anywhere from 1k-3k. 

We were initially thinking of renting our house and buying another that we would move into.

Will she charge me or can I just cut her something out of the deal?

I found some cold callers in FB groups charging only $4-6/hr.

Not for free, I would always charge them. 

Networking with these folks is a great way to learn what the big providers in your area are charging, and what they are charging for (extra for parking, storage, pet rent etc.)   

Initially tenants may not notice, but I do feel that it is more difficult to increase rates once they are in the unit. 

Here question to me below:BANKER RESPONSE: Just a quick note to say that I’ve reviewed your initial proposal and will be running some global cash flow numbers to see how they look.
