more about josh

Where the analytical mind comes from.

Engineering, then corporate, then an MBA in real estate finance — and an investment portfolio of his own. Four different vantage points on the same transaction.

Engineering foundation

A technical training that shows up in how he evaluates property conditions and reads a contract.

MBA, Real Estate Finance

A strong understanding of market trends, investment strategies, and financial analysis to help clients make informed real estate decisions.

Managing broker

Licensed as a managing broker in Illinois, with more than a decade of closings behind him.

Active investor

He buys and holds property himself, which means he understands the market from the client side and the owner side.

How josh works

Long-term relationships, not one-time transactions.

Clear communication, responsiveness, and genuine care at every step — the same standard whether it’s a first condo or a fifth investment property.

Buying a home

From a first purchase to a move-up, with the contract read line by line before you sign it. Josh walks the property with you, flags what an inspection is likely to turn up, and tells you plainly when a house is not worth the asking price.

Selling a property

Pricing, prep, and negotiation for sellers who have cared about a house for a long time. That means an honest list price backed by comparable sales, a short list of repairs worth making, and a marketing plan that puts the house in front of the buyers most likely to want it.

Investment property

Cash-flow analysis, off-market leads, and 1031 timelines from someone who runs his own portfolio. Josh underwrites a deal the way he underwrites his own: rents, vacancy, capital expense, and the exit, before anyone talks about an offer.

Joshua not only helped us find the perfect home, he negotiated and executed a deal very quickly within our budget and timeframe.  The area we chose is highly competitive and he acted quickly to make it happen.  Highly recommend JSN Realty group.

He and his team cleared out some larger furniture pieces, did some painting, and fully prepped the house for showing. Within 5 days we received multiple offers.  He managed the competing offers to land on the best deal, then he worked closely with us throughout the process to prepare for closing. We couldn’t be happier with Josh and his team at JSN realty!

To begin with, Josh was incredibly thorough, honest, and patient even when we needed to take a break from house searching to let the market breathe. We dove right back in with Josh and he never missed a step in matching us with an area that fit our needs. He’s helped plenty of our family members with their homes and they have nothing but positive feedback. Something that stuck out to us from these comments is the emphasis they had in saying this is someone you can trust and know he has your best interest at the top of his list.

 Trustindex verifies that the original source of the review is Google. We worked with Josh to sell our home. We sold our house within 2 weeks of listing it. Josh was exceptional at meeting us, getting to learn about our home, what is special about it, what aspects of it made it most appealing to buyers. He did a thorough market research, showing us what homes in the market can command in terms of list price and sale price. His staging, marketing and follow-up was outstanding. He was always on time for showing our home, working with other agents, and eventually securing the sale. We highly recommend Josh to help you sell your home.

 Trustindex verifies that the original source of the review is Google. Josh was a fantastic realtor. He went above and beyond to show many homes, often one at a time, when inventory on the market was very low. He is experienced and had solid advice on factors to consider and negotiating strategies, etc. Great communication and availability. He’s also knowledgeable about the nuts and bolts of home construction which provided helpful insights that many realtors can’t offer. Highly recommend!
