Since we also do renovations as a primary focus, I think we may be better-equipped than a lot of property management companies to achieve this.As for our tenants, we've had dozens who stay long-term because we DO respond to them and treat them like they matter.

All of those firms serviced clients such as yourself with hands in many activities. 100% anectdote as there are certainly many small firms and sole proprietors that can do it well, but at least in my experience the regional firm is by far best equipped to service those types of clients. 

I'm perfectly willing to overdo it on GFCIs with no equipment ground stickers, but I'm unwilling to go through the whole system and rewire a plaster house, or pay someone to do it.

Because they WILL go after you when the equipment fails and needs immediate replacement.

Do they provide their own equipment? 

Equipment: sheets of plywood for all downstairs openings, tools, empty boxes for their stuff, lock sets for every door, stack of 2X4's, long screws, nails, fake security cameras, no trespassing signs with California Penal Code 602 PC, gloves, masks, trash bags...If they won't leave, call the police (who won't help you but them showing up may make squatters run).  

Bear in mind, though, that an MBA is not going to really equip you with knowledge of real estate investing, and you’ll have to learn this.

HVAC equipment is typically landlord's responsibility unless it is a single family home and tenant agreed to all the maintenance - this is usually spelled out in the lease.

Hey Kathryn, This is my first post but I feel that I have experience in this so I figured I would try to help haha.I know in my area, Facebook Marketplace is a great spot to pick up used lawn or snow equipment.

I am going to dedicate one room with all the software and equipment where members can come any time to do their data mining, send direct mail, emails, crunch numbers and help each other by voicing opinions.
