Which home loan would you choose? 👇

Most buyers think waiting to save a 20% down payment is the "smart" move to avoid Private Mortgage Insurance (PMI). But the math tells a completely different story.

Let’s look at a $500k home:

Option A: Put 5% down ($25k) now. You pay about $170/month in PMI (roughly $8k over 4 years).

Option B: Wait 4 years to save 20%. Meanwhile, that $500k home appreciates at 5% a year and now costs $607,000.

By trying to save $8,000 in PMI, you just priced yourself out of over $100,000 in equity. 😲

Don't let real estate myths cost you a fortune. Math always wins.

💬 What's your strategy? Would you buy now or wait?

POV: You just landed your dream job in California… 🌴 but your current house is still sitting on the market.

Talk about a stressful reality check. 😅 Most people think they only have two choices: wait it out and risk losing the new job, or do a stressful double-move and rent in the meantime because their equity is trapped.

But there’s a third option. 🗝️

We recently helped a client tap into the equity of their current home before it sold. Because of that, they were able to:
❌ Skip the selling contingency
❌ Avoid a chaotic double move
❌ Buy their new California home right away

They moved, started the new gig on day one, and sold their old place on their own timeline. No life on hold. That’s the strategic difference. 🙌🏼

If you’re relocating and feeling stuck between two homes, let’s talk strategy.
