Justin, You can rollover your 401k into self-directed IRA, but not into HSA, which is Health Savings Account and not a retirement plan.There are several reputable providers here on BiggerPockets who are active on the forum, just search the forum for related keywords and you will find out who they are.

And because they buy "pretty houses" like me, they're a real threat.

These days I checked several threats in this nice Bigger Pockets forum and found several people have already asked about investments in Costa Rica.I know how real estate investing is done in the U.S. and I also know, that you can't use the same approaches and strategies 1:1 for Costa Rica (some strategies just don't work here).In Costa Rica I am specialized in high-yield investment deals (8%+) in the San José area and also in high-end luxury properties with great ocean views and good rental income potential in luxury tourism.One of my projects right now is providing a larger investor client/partner of mine with 8%+ yield p.a. real estate investment deals (in the 200k asking price area per unit) in great neighborhoods in growth zones in and around San José.

Several major health care corporations have moved their headquarters to Nashville.

My wife is a RN but has had to take an administrative position due to health reasons.

It is shocking how many landlords unnecessarily hand out money, when they could easily use threat of eviction to get them out.

If I were in your shoes, I'd probably have a frank and friendly with the tenant and talk a big, threat free game, but point out that her lease does not allow for animals and that she did not disclose the animal to you.

As to the income, many people on here can attest that it's actually not hard to live on $50k when you have no mortgage, no car payments, no other debt, you have health coverage, low taxes, etc, and fortunately that number goes to $60k next year without considering any other cash flow (purchase of rentals, may pick up part time work myself for extra savings, etc.).

Not to mention the parking garages and health facility they built for company use. 

Are you asking because you want to understand the financial health of the HOA or so you know which ones you should market too?
