Now my main issue is I need a fire detection system in a enclosed back porch that leads up to all three floors, but I don't know what's the minimum I would need to be compliant or that the fire marshall is suggesting what he wants or recommends.

It can take up to three days to serve, then you can file in court after the 3-day period. 

For example, below are three sections from the BP landlord forms lease.

For Airbnb, do i allow STR stays for the next three months and then block out the calendar beyond 3 months for MTR stays?  

I'd say each property on average has at least 2 bookings a week ( more during the on season) so that's about 34 hours a week average.

I think the reason most people "fail" or never start boils down to lacking one of these three things or a combination of them:A strong "why". 

Suppose you buy a $700,000 three-flat in Avondale with a $5,000/month mortgage and rent out two units for $1,500 each.

They also stated they only allow three brokers and three cash homebuyer “spots” in any given area, and they only move into areas where they can guarantee at least 600 leads per year.

They usually have a step down on that penalty like 3% year one, 2% year two, 1% year three and so on and so forth.So if you are buying a deal with the intention of rapidly increasing it's value in less than 24 months in order to refinance it and pull your cash out, you might want to go with a credit union for the acquisition financing because FCUs are barred from charging pre payment penalties.I could talk about this for hours about all the nuances but my fingers don't type that fast lol

Use the top three or four discriminators so applicants can screen themselves.Then you need to have clear screening criteria yourself.
