Good afternoon,Could anyone help me to estimate my monthly expenses if I rent out my single-family house in Sutton, MA?

Make sure you are using the estimated taxes shown at the Stark auditors site to check on them for next year as there are some significant increases coming!  

Are there any good resources online to be able to get an idea of average monthly/yearly expenses like utilities, etc. for a given zip or city?

If the rate is reasonable then it may make sense to try to save fast to get to the 3.5% down payment on a double or triple - househacking may allow you to increase your savings rate and pay down that loan even faster.As for estimating costs, closing in NY factor at least 1% of the mortgage amount for tax, plus $1500-2000 for lawyer, title and fees, then the amount required by the bank for escrow will depend on the actual property taxes and insurance.

The best way to estimate expenses is experience and knowledge of your specific asset type and market.For vacancy, that will depend on your market and the quality/desirability of your type of unit.

If you can get a loan at the 6.5%, you're saving another 5k a year off your estimates. 

We typically estimate standard costs for these items but get them done much cheaper with our own crew.

I'd estimate the current value of the property around $1M. 

It’s always a good idea to consult a local real estate attorney and title company for more accurate estimates in your area.

During your initial walkthrough, inspect the property for any major issues such as structural damage, roofing problems, plumbing, and electrical concerns, while documenting all cosmetic and functional issues with detailed photos and notes.Once you confirm the property’s potential, finalize your ARV and calculate the repair costs using either a reliable estimator or insights from contractors.
