So in your case thats standard or frankly a bit better than those that force equity and have money.. the idea though of selling these to those that dont have the 50k in cash or ability to get it is what puts these neighborhoods at risk and to ask and investor to step in and buy the asset and then resell it for 3X that investor is taking a huge risk ..

So for example, in the Orlando market, a 4bd house is pretty low as a standard but over here in the Tampa Bay Area a 4bd house is quite high on the STR ladder.  

I think 5% is a pretty standard rate to estimate with, but beyond that you might be higher or lower depending on your approach to landlording. 

I get the fact that they want to be compensated for generating the initial inquiry however, wouldn’t they just charge the standard 5% rate?  

If the unit is vacant, we don’t charge a monthly fee.For situations like yours, where the house needed extermination and other prep work, we would typically only bill for the costs directly related to the work or services provided, not a standard monthly management fee.Your expectations aren’t unreasonable—getting the house rented ASAP is a valid priority!

Hell, someone sent me an update today on sec8 payment standards in MSA where sec8 is paying dang near $4kmnth!

Hello, you can do some research with the city's planning department as far as their development standards for that zoning, i.e. set-backs, height, lot coverage, etc.

As a legit PM with a standard agreement in place, absolutely yes.

What I’ve learned in my first experience is Notice must be given to start the process but I am not familiar with what is the minimum standard for the Notice of Default.   

Get a development standards book so you can understand what and why a engineer should do something.
