They are old houses (like everything in New Haven) and no significant deferred maintenance, but things like adding AC/mini splits, parking spaces, in-unit laundry would definitely increase our rents.I'm inclined to grow the number of units first, then renovate as needed to maximize rents later, when we're closer in our lives to using the cash flow for ourselves.My spouse is more inclined to add all the extras to maximize rents now, and go slower buying new properties.Can anyone weigh in on either side?

1) many people bought at low interest rates and at only have a $1500 mortgage.2) others are using furnished finder as a way to subsidize the slower months (off season only)3) a small monthly cash flow can still yield huge long term gains in the form of appreciation, tax savings, tenant debt paydown, and leverage.

So far It's on Zillow, Craigslist, I have a 3'x 8' FOR SALE banner posted on the property, and I'm sending marketing materials to area commercial contractors, medical commercial contractors, urgent care chains doing business in NJ, and the same for dental. 

A large medical company just bought the hospital nearby and is projecting job growth of something like 15% in the next 10 years. 

I could see a market that goes sideways for a while, though. this recovery (or bull market) has overall been slower than others in the past.
