Hopefully you will have a lasting relationship with who you pick so if it isnt a good fit, keep looking. 

Hi Ryan,Wow parking for 30 dancing Zumba goers must make the street a true zoo(omba).30 friends getting together for dancing for fitness private party at someones house every Sunday after church, is different than using the property as a fitness destination business.It would be smart to ascertain which you have here.Simply telling her, your Sister wants to lose few pounds Zuba-ing--how much does it cost and can you have the join-up paper work for her might tell you what you need to know.

I've used Property Managers in the past and I will use them again because I understand the value they bring and it will better fit my lifestyle.

As mentioned above the first thing is which better fits your strategy, business plan and goals.

You will have to give the tenants the EPA required lead based paint paperwork anyway because its better that testing the whole house.I use mini-splits for HVAC in old houses--the ductwork will not fit through the crawl spaces and attics with all the room additions, so its much cheaper to put in the mini-splits and the tenants love having the individual room controls.For what you are proposing to do, you might as well just buy a vacant lot. 

Let local municipalities deal with local issues as their constituents see fit...

doing the property management should fit into my schedule fine.

Not all are like this but most fit into this category.

@William Zheng How you buy the real estate really will depend on whether you can find the deals that fit your investment criteria and goals.

If you find that they are the best fit for you regarding management and that's a trade off you're willing to work with, then sure.
