In other words you receive a 30% tax credit on the solar system as well as a 30% tax credit at the least on the roof that is under the solar system (full roof 30% depends on the advice of your CPA).Couple that with the roof now becoming a producing asset and offsetting the utility bill instead of a liability and the increase in appraised home value assuming the solar system is not leased then going solar makes a lot of sense at the same time as replacing/repairing a roof.So in short you don't "get a roof if you go solar", but there are certainly advantages to adding solar to a roof replacement.

Always make sure utility wise you have that all buttoned up as that hurts your noi.

The problem would be getting them to commit and look at this, I know a lot of management firms utilize these deposits for extra revenue but they need to be fair and give you every opportunity to correct. 

Zoning, what utilities are in place or are available, easements, views,  and what a buyer would intend to use the property for are all important factors. 

Make sure you run the numbers for what new construction residences are going for, and subtract out construction costs, cost to install utilities, developer profit, etc, and you can get an idea of what a developer would pay for the lots. 

My intent is to do some rehab, increase cash flow (rents, utilities, etc) and resell in 12-18 months.

In your case you are just waiting until you finish the separate utility items.Hope that helps

Do they pay for utilities?

Bought our first duplex and are going to utilize a live in flip BRRR strategy.

. $9,450. 30-year fixed, Interest Rate: 5% Rental Income: $3,900 We will be living in one of the units, but for the sake of the analysis I am going to calculate both units as rental income and factor in my costs at the end.2 Unit: $1,600 + 3 Unit: $2,300 = $3,900/moTotal Expenses: $2,832 Operating Expenses: $1,434/moMortgage Expenses: $1,398/moResults Monthly Cash Flow: $1,067/moMy Unit’s Rent: - $1,600/moOur Cost of Living: -$533 / 2 house hackers = $266/mo.Biggerpockets Property Rental AnalysisIn conclusion, if this house hacking plan is accurate and realistic, I would cut my monthly living costs from $850/mo to $233 (excluding utilities), and would have purchased my first rental property.
