Sell or Hold Rental Property

[Marc Appel]

I own a single family in Waltham, MA. 

Mortgage taxes and insurance are $2,173 a month. Rent is $2575 a month. I purchased the home for $346K and is now worth around $450K. Currently 13 years left on the mortgage. Windows and siding need to be replaced for a total of 25K. I have already put 25K into the home. Do I put another 25K in and hold for a long term rental property or sell the place as is if I can get $450K? If I sell I would use that money to invest in a multi family. 

Thank you very much for your time,

Marc
