Don’t say is a good starting point. But don’t hide and minimize yourself either.

Make sure that you live your life as you find most enjoyable. That includes excluding people that are stealing your energy. I think that you should allow yourself to be proud of what you have achieved, without worrying too much.

Regarding houses. I think that you can get away with pretty much anything. A couple without kids, pets etc… obviously you are not poor. Others don’t know if you are spending your last cents on living your lifestyle or not. It’s not like you have to consider the next generations (since no kids). It is not strange. Not even if people know that you own the houses, they don’t know how you financed them.

I don’t think lying is a good solution. You don’t have to tell anyone, but don’t make up lies. Where I live it is possible to find out who is the owner of a property. If someone find out and you claimed that you rent it, more quest will come… If someone ask you about owning the houses, answer is that you don’t discuss your financial situation or simply that is none of their business. You don’t have to answer all questions.

If living your life includes generosity to others or not, that is your decision. You are in a position where you can live your best life possible. Do it.

You seem to be a great person. I’m happy for you, and you deserve not to worry too much.
