Deciding on whether to raise the rent or not for properties in DE

[Buyan Thyagarajan]

Hi Guys,

I have a rental property in Wilmington Delaware which is a single family home for $1550 rent. My current tenant wants to renew the lease but says he will pay the original rent. I have new offers from zillow at $1600 plus. Looking at Zillow the average rental in my area is around $1600. What do you guys generally do for tenants now who have stayed for a year and want to renew the lease? I am also concerned on risks on Covid and lose the tenant.
