New Construction vs Old what appreciates better long term?

[Jorge Martínez]

Hi, I am actively looking and putting offers for my first rental property, I just saw a townhome that I like from the 70's that needs some rehab, and a few blocks from it there is new development offering same type of units (a bit bigger) 10% more expensive with delivery lead times of 6 months. My strategy is long term appreciation with breakeven cashflow (for now), so the question is what do you guys think is a better investment long term?  Thanks
