For example how much to reserve for management fees (I don't have time to host myself), cleaning, electricity.  

It really depends on whether you prefer the hustle of managing STRs or the steadier income from LTRs.My TakeIf you’re drawn to the energy of the STR market and love the idea of working where people vacation, Florida might be the way to go.

But it takes time and energy from internally motivated people who take responsiblity.

Electricity can also spike in the summer with A/C.

Quote from @Anade Davis: I was not looking to say anything negative but the energy is off.

An example of that is tenant must pay for additional electric over flat fee / flat limit since now there is 2 occupants in the home instead of originally one.

The energy in person is different for me, and I've made some of my best connections and friends at Chicago meetups.Here is a list of the Chicago event from BP: https://www.biggerpockets.com/forums/521-real-estate-events-...I also have a list of ALL THE CHICAGO MEETUPS that I am happy to share with you. 

For example, it's difficult to appease a situation if 1 tenant claims they're using less electric/gas than another. 

Yes because lot of time and energy save we hire team for fast work.

I carried double the cost on Gas and Electricity to be safe. ==== Projected Income ====**Off Season**-$4,000/Month Rent Period: September - May (7 Months) Projected Income: $28,000**Summer 1**-$8,000/Week Rent Period: June (4 Weeks)Projected Income: $32,000**Summer 2**-$8,500/WeekRent Period: July-September (12 Weeks) Projected Income: $102,000**Optional** (Basement Apartment)-$2,000/Month -Rent Period: Year Round Projected Income: $24,000TOTAL PROJECTED INCOME: $186,000 ==== Operating Cost ====-Mortgage: $84,000 ($7,000/Month) -Utilities: $36,200Gas $6,000 ($500/Month) Electricity $6,000 ($500/Month) Internet $2,400 ($200/Month) Garbage $5,000 (Estimate) Pool $4,000 ($250/Week)Landscaping: $4,000 -Mowing: $2,400 ($150/Week)  -Clean Ups: $1,600 (Spring & Fall)-Weekly Turnovers: $8,800 ($550/Week)==== Legal Cost ====Summer Rental Fee: $20,100 (15% of $134K)Sandwich Rental Tax: $6,855 (15% of $45,700) NET PROFFIT: $38,845.00
