You gone bleed yourself dry at those numbers. 

If it became an issue when time to sell I would just blow out the door into the main house and sell it as a 6br 4 bth.

Those who blow it off eventually lose eligibility.To ignore the correlations is nonsense.

One of them hired a landscape guy, well, the landscape guy never came so I was paying $140 per month for nothing for about 7 months.The other property manager didn't tell the tenants they were responsible to replace the ac filter, that bill was $1000 to replace the AC fan motor.I am really afraid of blowing off the money.

If you seem like you are just gathering information to self-manage than they will likely blow you off.

Effectively a 'Firestorm' is a dry hurricane that rains fire, with nearly indefensible circumstances, just like the catastrophic flooding, hurricanes, tornadoes and other disasters they have and will intensify in severity and rapidity.Beyond directly impacted property owners, investors, insurers and businesses, the downhill effects of the SoCal fires on the immediate and surrounding areas are astronomical and still somewhat incomprehensible.

By the most important thing (if that's what you're doing) is to have a really good operator who knows the laws, has experience and is above board so they won't leave you high and dry. 

I've filled out those little "Enter to Win" cards at the mall for a new car and had timeshare folks blow my phone up for the next 3 months.

The mileage rules aren't as cut and dry for landlords as they are for people who have a regular W-2, office job.

The wrong chemistry, well, see what happens if you put a few drops of brake fluid into dry pool chlorine (actually, do not do this!).
