Say that you're considering Neighborhoods A and B because you've read that they have a strong ROI but arent too dangerous.

There's very little danger to cleaners or future occupants unless it was a meth lab.

There are lots of bad contractors out there; fewer good ones.

Some things you can do is charge a flat rate and cover the difference or call the utility company and get a 12 month average and make that a part of the rents.3: Personally I don't believe in furnishing or supplying anything for my rentals because my market simply doesn't call for it.4: Depending on your area and what the replacement cost for that building is, inflation can effect your policy differently, for this one I would call your provider and ask.5: Common areas much like an HOA would charge, put a common element/area clause in the lease stating the tenant is responsible for a percentage of costs for upkeep of common areas.6: This may depend on state laws, but I would look into if your area requires ADA compliant signage but if you wanted to put a no smoking sign so long as it's stipulated in the lease then it's your call.7: You can't always do much about guests so long as they don't stay indefinitely or cause a danger to other tenants.

I have worked on the Westside for the past 4 years, so I am very aware of the potential dangers of this area and specifically, the parts you don't want to hang around in after the sun goes down...I really like the Springfield area, as it seems to have significant potential due to expansion of local businesses, in addition to being in very close proximity to a handful of large hospitals and predominant businesses in downtown Jacksonville.

Fewer sellers who'll sell on a lease option since they have equity and a nice house they can list.   

You may want to try a company like State Farm that allows dangerous breeds.

@Devin Mann  I would agree that there are at least more sales in a bigger city and fewer days on the market (DOM).  

I know enough about this to be dangerous...Here is a link that shows which states have enacted legislation and you can see it all relates to exemptions for crowd funded transactions.

We relocated the alarms and had fewer alarms to fix or replace..Our maintenance tech always checked and serviced any dangling detectors or missing ones if he was in unit for any type of maintenance..
