About Mark Nesci, Chicago North Shore Realtor
Realtor. Mortgage Banker. General Contractor. Serving Chicago's North Shore from Highland Park, Illinois.
Most agents only understand one side of the transaction. Mark Nesci understands all three: real estate, mortgage banking, and general contracting.
Mark Nesci brings a rare combination of credentials to every transaction. He spent 15 years in mortgage banking, where he learned how loans are actually underwritten and how to structure financing so a deal holds together. He spent 14 years developing residential properties, which means he has personally overseen construction, renovation, and teardown projects from the ground up. And as a licensed general contractor and lifelong North Shore Realtor, he evaluates every home through three lenses at once.
That background changes the conversation for both buyers and sellers. For buyers, it means financing strategy before you tour, spotting construction issues during the walkthrough, and realistic renovation scope estimates before you make an offer. For sellers, it means pricing grounded in true condition, pre-sale improvements that actually return value, and a home prepared to stand up to a buyer's inspection without surprises.
How Mark's Background Helps Buyers
- Financing StrategyFifteen years in mortgage banking means Mark can explain jumbo qualification, reserve requirements, and how your income and assets will be underwritten-often before a formal application.
- Spotting Construction IssuesAs a licensed general contractor, Mark reads inspection reports like a builder, identifying structural, roofing, mechanical, and electrical concerns that most agents miss.
- Estimating Renovation ScopeFourteen years of residential development means Mark can give you a realistic read on what a kitchen, bath, roof, or mechanical update will involve before you commit.
How Mark's Background Helps Sellers
- Pricing Grounded in ConditionMark prices homes based on true structural and mechanical condition, not just comparable sales, so your listing holds its position under scrutiny.
- Pre-Sale Improvements That Return ValueHe identifies which updates remove buyer objections and photograph well, without overbuilding for the neighborhood.
- Preparing for InspectionsMark addresses inspection-level electrical, plumbing, and moisture items before a buyer's inspector finds them, reducing renegotiations.

Needless to say, the house was sold quickly and smoothly."
