How are landlords in SF handling the security deposit law that requires them to pay interest to residents on their deposits?

Keep in mind you need so many different website plug-ins and features and you have to make it secure for credit card processing.

Also, what about internet, trash and security?

@Joshua DunlapRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?

The vast majority of lawsuits against Landlords are for wrongful eviction, security deposit disputes, and Fair Housing Violations.

The short version is this:  If you're willing to pay (considerably) more for the security of guaranteed rent, they are probably worth hiring.

It's the same thing from a dollar perspective as it's just the accounting classification of funds, but since they applied the security deposit to the rent they also took part of the security deposit as late fees for themselves which just feels wrong since they didn't actually get the rent, but just applied the security deposit. 

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

The vast majority of lawsuits against Landlords are for wrongful eviction, security deposit disputes, and Fair Housing Violations.

For instance; depending on the price range of the unit, people may be buying a place to call home; or they may be buying a sense of security that is economically stabe and affordable; or they may be buying, in the case of a luxury rental, prestige and a sense of accomplishment in life.
