Jose, I am not in your shoes. A good friend of mine here in the USA is, however. His wife is from abroad and from a very traditional university-educated background with an extremely rigid European mindset -- she simply doesn't understand why he bought a cheap place to live in and fix up. In her view, he should have taken out an enormous mortgage on a palace and paid it off slowly over thirty years with the peanut salary that he would made working tirelessly as an office drone at some faceless company.
Now get this, my buddy has already paid his little house fully off, five years after buying it. With my help, he's getting a home equity line of credit on this place and is looking for a tax foreclosure to fix up and move his growing family into in one of the top three school districts in my county, because he knows the right opportunity will come along sooner or later, and he'll be ready to jump on it and get a small, fixable property at 30-40% of ARV. He's also completely changed careers: he went from a job as a nursing assistant into an HVAC apprentice position, a lateral move with no money increase at the moment but wonderful future prospects, especially as he intends to stay in the house fixing business and continue working with me. But his wife doesn't see, can't see it, refuses to see it. And as I'm sure you understand, his wife's family back in Europe isn't helping much.
What the wife doesn't understand is that residential housing is her husband's BUSINESS, not his EXPRESSION OF SOCIAL STATUS. This is a remarkably difficult point to get across. Your parents are the same way, and there's no way you're really going to change their perception. You can show them numbers a child should be able to understand all day long -- there's a huge, monstrous, built-up mental block in them to understanding your HOME AND HEARTH is not, by conscious choice, your personal EXPRESSION OF SOCIAL STATUS. It's an entrenched cultural neurosis.
The only solutions to this, I believe, for my friend's wife, for your parents, are absurd ones.
First of all, there are temporary fixes. Buy some nice clothes. Buy a nice watch. Waste a ridiculous amount of money on a late-model car instead of a sensible used one. All this will make your parents feel a bit better when they see you outside your home. I know it's stupid but it works.
But the real solution is the crass truth that QUANTITY HAS A QUALITY ALL ITS OWN. Once you are running two properties, three properties, four properties, the blinders come off, and there is enormous intellectual liberation watching it happen. "My son owns four houses" or "my son owns and rents out six apartments" is a very powerful, complaint-stopping statement in American society. You go from being a dumb house hacker to being a smart real estate investor. Once you get to "my son runs 40 units all over the Southern Tier," you will see a deep, powerful respect glowing in their eyes when they speak to you, their endlessly brilliant son, a man they tirelessly proclaim is the best thing they've ever done with their lives, and they will go on and on and on about how much they contributed to your success through the wise choices they made during your upbringing. A great son, doing great things in the world.
It'll be more than enough to turn you into a cynic.
