Typically when we look at acquiring a property, we underwrite a reserve for any capital expenditures that may come up in addition to at least two months of mortgage payments, which typically included taxes and insurance. 

I factor in capex (even if I didnt have a cap expenditure that year), maintenance, estimated vacancy usually 8% of gross rents, and sometimes property management fee since managing a rental isnt free whether my time or someone else's. 

Every month I'll put money aside for vacancy, maintenance and expenditures(furnace, roof, etc).

The reduction in monthly expenditure will create space in your budget for increased savings and investing.With all things in investing, there are trade offs. 

Are there any capital expenditure things? 

You seem focused only on the tax side, without regard to how much revenue the big-ticket expenditure is going to bring in.
