I have helped my elderly neighbors before, for free. Cutting their lawn, trimming, power washing their driveway etc. Mainly because their wife/husband had passed away and they can't move around and living on a fixed income, meanwhile the surrounding neighbors are hounding and harassing them for "devaluing," their property. But in this case, it sounds like they just want little to free labor just so they can save money on expenses that they should definitely be paying for when it comes to renovating their property before putting it up on the market.. I have a soft spot for the elderly but this one is a hard pass.
