Martin Castro-Silva spent 12 years as a private client banker at Chase, sitting across the table from wealthy clients in South Florida and noticing a pattern: The ones doing the best were almost always connected to real estate.\u00a0<\/span><\/em><\/p>\n

One young client kept coming in to wire money for <\/span>house flips<\/span><\/a>, walking away with $20,000 to $25,000 in profit in a matter of months. Martin started asking questions every time the guy walked in.<\/span><\/em> He <\/span>refinanced<\/span><\/a> his home to pull out capital, <\/span>got introduced to<\/span> a wholesaler, and bought his first flip in February 2022.\u00a0<\/span><\/em><\/p>\n

Four years later, he’s done 11 deals in a single year, moved his family to a more affordable market, and stopped working weekends entirely.<\/span><\/em>\u00a0<\/span><\/p>\n

Here’s how he built it.<\/span><\/em><\/p>\n

Your first deal took seven months to renovate. What did the numbers actually look like, and what did you learn?<\/span><\/h2>\n

My mom and I bought a townhome in Lake Worth for $200,000 using her refinanced <\/span>home equity<\/span><\/a>, split 50% cash and 50% hard money at interest-only terms. It only needed about $25,000 to $30,000 in work, but since I was still working full-time at the bank, it took seven months to finish two bathrooms and a kitchen, and we paid roughly $7,000 in holding costs during that stretch.\u00a0<\/span><\/p>\n

We listed for $320,000, gave a small concession I didn’t need to give, and closed at $310,000. Even with all the delays, I netted $37,000, which was close to half my annual salary from a single deal. That was the moment everything clicked.<\/span><\/p>\n

You quit your job mid-renovation on your second deal. What gave you the confidence to make that leap?<\/span><\/h2>\n

I didn’t want to keep missing moments with my kids, who were 1 and 3 at the time. I showed my wife the spreadsheet from the first deal, the actual numbers, and told her worst case, I could always go back to corporate.\u00a0<\/span><\/p>\n

I bought the second property, a single-family home two hours north, for $170,000 using a line of credit I’d taken out against my own house. I budgeted $40,000 for renovation and ended up spending $50,000, which wasn’t bad for my first full single-family gut job.\u00a0<\/span><\/p>\n

The real lesson came at sale time: I overpriced it at $325,000 to $335,000 against my agent’s advice, turned down a $300,000 cash offer in week one, then sat on the house for four months before finally selling for exactly $300,000 financed. I still profited $35,000, but I paid for that lesson in carrying costs.<\/span><\/p>\n

Your third deal used a cross-collateralized private loan. How did that financing structure actually work?<\/span><\/h2>\n

I didn’t have cash left after the second deal, so I went back to another bank client of mine, an agent, and offered him the deal: If he lent me the money, he’d get to list the property when it sold.\u00a0<\/span><\/p>\n

He gave me a $150,000 <\/span>hard money loan<\/span><\/a> using my first single-family house as collateral. I applied what I’d learned about pricing and listed this one at $299,000 instead of overreaching, and it went under contract in six hours. I closed that deal and the second one in the same week.<\/span><\/p>\n

Your fourth deal came from a neighbor of one of your own renovation projects. How did that connection turn into a deal?<\/span><\/h2>\n

I made it a habit to tell everyone I met that I bought houses, including neighbors near my active projects. I told the neighbor next to my first single-family flip that I’d help him sell whenever he was ready, and months later, he called.\u00a0<\/span><\/p>\n

I bought his house for $150,000, which was $20,000 cheaper than what the wholesaler had originally sold me a comparable property for, and it even had an extra room. This time, I partnered with my siblings, who’d seen my results and wanted in, and we bought it in cash together. We put around $55,000 to $60,000 into the renovation and sold it for $320,000, netting about $65,000 split three ways.<\/span><\/p>\n

What does your buy box look like now that you’re doing 11 deals a year, and how has real estate reshaped your life beyond the deals themselves?<\/span><\/h2>\n

I only buy in Vero Beach and Sebastian now<\/span>, <\/span>single-family homes around 1,200 square feet, three bedrooms (or two if the square footage allows adding a room), purchase price between $150,000 and $220,000, <\/span>with<\/span> a resale value under $350,000.<\/span><\/p>\n

That price point keeps me safe: If a flip doesn’t sell quickly, I can <\/span>always<\/span> rent it and roughly break even instead of bleeding <\/span>hard money<\/span> interest.<\/span> I <\/span>actually<\/span> moved my family to Vero Beach after realizing that’s where my deals kept coming from, <\/span>which<\/span> also got us a bigger, more affordable house.<\/span>\u00a0<\/span><\/p>\n

I now have a renovation crew handling the day-to-day rehab work, and this year, I stopped working weekends entirely. Saturdays and Sundays are just for my family.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
