Right now we are just finishing out this year before we really put the gas pedal to the floor. 

I ASSUME you’re talking $400+ in extra expenses for providing water, power, sewer, gas, internet, communal area cleaning, and exterior maintenance.

Licensed with permits ~$3,250.HWT standard gas single family low efficiency without exhaust retrofit $900.Sand and stain hardwood floors, natural stain $3 per sf.Paint interior walls, ceiling trim and doors 3 tone paint scheme 2 coats $3.20 per sf (floor area cost includes paint)Click lock LVT flooring install overlay inclusive of prep and quarter round $4.50 per sf (materials and labor)Asphalt roof installation 3/1 - 800 sf bungalow with 2 layers of shingles - ~$7,900Standard porch cap replacement with 2 new precast concrete steps ~$2,500Used stove or refrigerator delivery and install $350New stove or refrigerator delivery and install $HD model specificUse this as a general guideline. 

There are options you can invest in such as oil and gas, datacenters etc. that typically provide significant depreciation.

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

Our electricity is already separate and we designed our ADU to be all electric so no gas. 

Just remember that $70 is the gross number they charge , they have to buy supplies , insurance , tools , vehicle , gas , workmans comp etc . 

One of the utilities, South West Gas, based in CA, gave me a hard time putting the account into my own name. after several calls, faxing the court-stamped eviction order, verifying my deed through the County, etc,  the operator finally agreed and started to backdate the account change to the beginning of the process!

I also have five gas/electric meters.

Mark down all the multis you see by looking for two or more doors in front or multiple air handlers outside or gas meters.
