You've probably heard of big Landlords losing property, but only because they were flagrantly violating Fair Housing, running a slum, or otherwise violating the law in an egregious manner.

A lawyer might be able to answer this better, but most rentals fall under fair housing laws (there are exceptions) and that protects against discrimination based on familial status which means children or someone who is pregnant.

Your state law and notice can be found online. 

Eventually I want to get into single family and multi family rentals.As far as effort or work on the fixers;  my brother in law is quite handy and my next door neighbor has said he would help in anything that is out of my scope of expertise. 

This has been our primary business for well-over thirty (30) years, but in California ONLY.Few posters here are attorneys, let alone licensed to practice law in Hawaii.

Kyle  My father-in-law did this by creating a portfolio that is primarily debt-free single-family rentals in the city he lives in.

So you want to check that out.I also ask how familiar are you with Spanish, and reading Spanish contracts, and knowing landlord/tenant laws in Spain? 

I'm sure over time more laws will be created to force the government to give that information in a more timely manner but for now they often obstruct the public by withholding it for a time.

There are certain areas and strategies for that (and city laws you should be aware of).

I could connect regarding refinancing and buying a new property in order to maximize profits and also talk regarding the upcoming laws the city passes regarding multi unit properties.
