Section 8 tenants and rent increase

[Joshua Kohl]

I’m under contract on a duplex and one of the tenants is section 8. They are due for a rent increase that has not been completed by the previous owner. How do I go about following through with the rent increase? The HUD FMR is higher than I think my area will support. The amount the current tenant already pays is preset by HUD, correct? So, the increase in pay would come directly from HUD?
