Real Estate
Without the Guesswork.
Practical tools and real-world guidance for buying, selling, maintaining, and investing in residential real estate. Built from decades of hands-on experience remodeling homes since 1988, working in real estate since 1998, opening a brokerage in 2000, and becoming a general contractor in 2015.
Better real estate decisions start with understanding the numbers.
Know the cost of selling
Commissions, closing costs, repairs, concessions, and financing can materially change your net proceeds. Use the tools here to estimate the numbers before making a decision.
Understand the process
Whether you're buying, selling, maintaining, or investing, understanding the terminology and sequence of events makes it easier to ask better questions and spot potential problems.
Local rules still matter
Contracts, disclosures, licensing rules, and customary practices vary by state and locality. StartProjectX provides education, while local professionals can address requirements specific to your transaction.
Learn the property from four angles
StartProjectX organizes real estate education around the decisions homeowners and investors make most often: buying, selling, maintaining, and evaluating property.
Buy
Learn financing, contracts, inspections, appraisal, and the costs that shape a home purchase.
Sell
Understand pricing, preparation, marketing, offers, commissions, and the path to closing.
Maintain
Plan repairs and maintenance with a better understanding of useful life, priorities, and likely costs.
Invest
Evaluate purchase price, repairs, cash flow, resale assumptions, and different investment strategies.
Real Estate Decision Tools
Explore selling costs, FSBO preparation, and investment numbers with interactive tools designed to make the underlying math easier to understand.

Decades in the field.
Not the classroom.
StartProjectX is built for homeowners across the United States. The principles here come from first-hand experience buying and selling homes in New York, North Carolina, Tennessee, Maryland, and Virginia. State laws, disclosures, contracts, and closing practices vary, so local legal and licensed professional advice still matters. This isn't theory from a textbook. Every strategy, checklist, and piece of advice comes from real transactions — remodeling homes since 1988, working in real estate since 1998 and opening a brokerage in 2000, and holding a General Contractor's license from 2015 until retiring from contracting work. Both the broker and GC licenses are currently inactive.
"I got tired of watching homeowners hand over tens of thousands of dollars in commission when they didn't have to. There's a better way — and I've spent 35 years proving it."
