I built myself a calculator to analyze deals and I wanted to run this property past you.

After doing the math using the calculator I should sit at about 9.5-10% ROI. 

Any home warranty you'll buy will calculate the age of your major expenses and cost you the price of the products you're looking to replace.

How can I calculate property taxes?

You can then sum up your overall cash flow shortfall over the period until release, to calculate how much capital you need to reserve to keep you afloat.

The answer is "None, because according to our calculations the light bulb doesn't need to be changed."

The lender on your investment property 1-4 units, will consider the additional debt payments but also the potential rent  (i have heard anywhere from 50-100% of rent depending on the lender) on the property to calculate your DTI.

I do not believe you need a 1% property (1% rule) to have positive cash flow as there are many variables that determine if a property has positive cash flow, but I do believe it is a very rare market that has cash flow at investor LTV (at least 75% LTV) noticeably below a 0.7% ratio.Now for this ADU: $290K for $1.8K rent (on my calculations I will always use the more conservative of values) is a ratio of 0.62% (far below my 0.7% ratio that I indicated it would be a rare market to have positive cash flow).
