When underwriting I usually use 5% of gross rent for cap-ex, vacancies and maintenance as place-holders/quick rule of thumb absent better data.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

Most buyers find it more attractive to purchase a place that has some future income built in when they buy it.

Keep in mind this will be a 30 year or forever hold with appreciation the ultimate goal and cash flow at year 20-30 being retirement income (hoping to stack 10 of these if i can)Here's the numbers, I'm planning to close in April i just got back from taking the wife and kids to the build site, they approve so that's nice haha.

You can rent it to yourself, but then you would also have to declare that income, so it becomes a wash and not a write-off?  

Actually, given the opportunity to generate rental income and the potential for risk reduction via diversification, modest multifamily residences could be a prudent investment.Kindly feel free to ask any specific questions or seek advice before starting your next real estate venture.
