Jesus only mentioned tithing to illustrate how hypocritical the Pharisees were but you can bet most preachers won’t preach it that  way .just like when you hear of the parable of the “ widows mite” preachers are quick to say it’s an example how we should do sacrificial giving down to the penny  like the old widow did when it was actually when understood in context as another example of Christ calling out the Pharisees and how they extort people !   

Of course, this is just my opinion but I bet I'm not alone..If I'm an investor, I think the returns you're able to achieve in Costa Rica are higher than normal because you focus on these large properties and, as @Martin D. mentioned, prices in that country are too high and returns too low.

Furthermore, this rule may be disregarded as investors become more creative.For instance, if investors intend to buy and make a long-term hold play, betting on appreciation, they may be able to afford to pay more.

You want overnight money, go bet on penny stock small cap biopharma and biotech stocks.

If I was a betting man I would say the answer to that question is NO and they are likely promoting the 2-3% success stories as the norm and therein lies the problem. 

Right now I think your best bet is to call your insurance and go through them.
