That is a significant difference.I've read numerous times that investors who don't set enough aside for maintenance and/or big ticket items often get hit hard and go out of business/go broke when big ticket items do pop up.

I get charged 10% on property management per rented property, lawn maintenance and service utility on the properties not rented, and miscellaneous expenses on little things that pop up for maintaining the properties.

Now, a Mom and Pop style PM.

Most economists would call this a bubble and when it pops the prices come crashing down to the level where they should be. 

having an incredible onsite manager, adding colorful flowers to perk up the curb appeal, paint the windo shutters to make them pop and renovate the interiors.

Documentation is very important, and sometimes an issue will pop up later and you will want photos to reference back to.I would also add to be conscious of the tenant’s privacy and remember that it is their home too.

Plus, it’s hard to ignore a notification that pops up right in front of you.

I have NEVER had any SFH take more than 60 days, EVER, and I have popped tops, done major 6 figure flips, huge projects. 90+ days is mis-management unless your doing a community.

But if you know of brokerages who cater to investors, that's good, but more likely they are mom and pop because the big brokerages want it all.
