To raise the rent or not?

[Nikki Taylor]

We have a single-family home that we rent out to a lovely family. They've lived there two years and have been really great tenants. Recently our house was reassessed and our taxes are going up around $600/year. While we could just absorb the extra taxes and still run a profit, we'd of course rather not and are considering raising the rent by $50/month. The rent for the house is on the lower side for the neighborhood already so even with the increase it's still around the low end of average. But I know our tenants aren't rich and this may be a source of strain on their finances. In general we don't want to be raising the rent and would just keep it the same as long as our costs don't increase but given the increase in taxes, it seems like the time to raise it? Though of course we don't want to lose our awesome tenants. What would you all do?
