FHA required repairs are limited to those repairs necessary to preserve the continued marketability of the property and to protect the health and safety of the occupants, AKA the three S's: safety, security, soundness. So having a stove depends on what's typical in the market, and what makes a property marketable. In some markets, stoves are considered part of the real estate, whereas in others, they are not. If stoves are typically sold as part of the real estate, then there is a market expectation to have a stove, and a property may lose marketability without a stove. (Although REO sales may seem typical in some markets at this time, I would not consider them to be a "typical" sale; note the words CONTINUED marketability, above, which extends beyond the current down-turned market). Although FHA may not have a specific requirement for a stove, the property must maintain continued marketability (which falls under SECURITY of the FHA insured mortgage).
An exhaust fan may fall under the Safety requirement if there is a local building code requiring exhaust fans. Again, FHA does may not have a specific requirement for an exhaust fan, but the property must meet minimum building code requirements for the area. As an FHA Certified Appraiser, I spend a lot of time researching and understanding local building codes as they pertain to each property - that's why I get paid the big bucks lol ;-)
