 I'll respectfully disagree with the "no benefit to cash" statements.When I'm representing a seller, we LOVE all cash deals, because it eliminates the whole underwriting process.That's where deal get wrapped around the axle - borrower's DTI changes before closing, property appraisal comes in low, property is with 300 feet of a gas station (yes, that's a real thing with FHA), sudden unrelated expenses come up during underwriting and borrower has insufficient cash on hand to close, down payment cash is gifted from a source the lender won't approve of (think close friend, second cousin), cash gifts are not seasoned, FHA/VA/USDA appraiser sees peeling paint, broken window, crumbly steps, etc., not to mention that it also eliminates the financing contingency.A cash buyer eliminates all of those landmines, making it a MUCH stronger offer than one with financing, even if the all cash offer is somewhat lower.

Maybe you can help me eliminate some of those troubles.

However we were also told we could not eliminate all baseboards so we would need to upgrade the electric.
