We learned that a LOT of people are willing to get rid of their father's or mother's home for a song because they can't come up with the tax money to keep it.I would say we do much the same sort of thing these days but our focus is shifting to finding small multifamily where the landlord just doesn't want to go on with what he has.

We are in Encinitas and have to go to SJ to care for my mother n law and thinking of doing RCFE or STR in our primary.

Sorry, VERY wrong again. the most sought after individual's for lawsuits. the sweet spot are your average investors (neighborhood millionaire) {contractor, lawyer, doctor, nurse, etc) who just turned the corners with assets, of 1 million to 3 million who now has tons to loose from just the threat of a lawsuit let alone an actual judgment.

I have a MTR/STR in Arlington, we have hospitals nearby for travel nurses and plenty of tourism that brings people to the area.  

My mother gave me a house she bought in 2010, and its value has increased significantly since then.

My issue is with the ones who don't do any research beforehand to ask a better question.A new person asking about house hacking a multi vs. a mother-daughter is a great question, and they have narrowed their scope and are doing the work.A new person asking how to get into investing is just being lazy and hoping for a Doug Flutie hail mary to land in their lap.I think of it as, how do you want to show up and appear to other people, in any forum?

For example, if you're looking for travel nurses, you'd note that your listing has blackout curtains, a white noise machine and near hospitals (those are important details for them).

Let me give you an example, you have a client that works 7pm-7am (think of a nurse or doctor), they tell you they are really only available to physically go and look at properties 8a-10am or 3-6pm.

It would also be possible str if I get an adu or mother in law basement. 

Even if your mother approves using some equity from your home as a down payment for a second property, you will still need to qualify for the remaining amount needed for the purchase.
