I’m looking more for emerging markets, up and coming areas, where I can jump on early and reap the benefits.

I recently had a sewer line repair that was an emergency, our main line basically disconnected from the city line - full blockage. 

UNLESS, they lump in the "emergency repairs" that were already done (the tree removal and tarping of the roof?)

Explore the potential of Directly Participative Ranch Investment Programs to emerge as a prominent trend over the next decade.DPPs offer a unique opportunity for investors to directly participate in ranch ownership, enabling them to diversify their portfolios and potentially generate passive income.

Also, no heat is an emergency.

The PM does have a responsibility to take action in an emergent situation.

I've been in property management for over 25 years and unless you are okay being burdened with the responsibility of chasing rent, collecting rent, filing in court for rent, assessing & scheduling repairs, vetting contractors, handling emergency calls 24/7, etc., you need a professional to handle these things for you. 

Also, a tenant must document non emergency maintenance issues in writing and the landlord has 30 days to cure.

If you don't have that cash (plus any cash for expected repairs, plus any cash for a $10,000 to $15,000 starting emergency reserve), you may find this business very painful from time to time. 

If you didn’t, then it’s non permitted use and you may run into issues not just with mail, but also think about emergencies and if there’s no address then it will be more difficult to locate anyone in the property.
