Should I negotiate rent?

Hi everyone, I have a question about negotiating rent. I live in New Jersey and rent an apartment from a medium-sized property management company. We’re interested in renting another property from their portfolio and are wondering if we should negotiate the rent. Our current rent is around $1200, while the rent of the other unit we’re considering is about $1900. The unit we’re looking at hasn’t been renovated in over a year, but it includes heat, hot water, and gas. I’d say it’s not much larger than our current unit, with no more than 200 extra square feet (an additional bedroom). Since we’ve been with this property management company for over four years, we’ve never missed a rent payment, and we consider ourselves responsible tenants who keep to ourselves. Should we negotiate the rent and ask them to lower it by $150 a month, which would bring it down to $1750? Any advice would be appreciated!
