Personally if you are looking to grow in real estate going the traditional method/way of getting good properties under agreement with traditional financing will get you to where you want to go faster than trying to find all the needles in a haystack.

Personally, I like to use Notion for this type of task, but I'm sure there will be others on here that will recommend Monday.com, ClickUp, or Asana.

I've only had one person look at my home. 

@Grant Shipman Great stuff, I'm a big fan of co-living/rent by room strategy, and I do it here locally in Denver metro, and it is the best strategy in today's market for any house hacker to live for free or make money while living there, but they have to sacrifice personal space.

H there, I'm a certified international property specialist and while i don't personally specialize n Costa Rica,  have several colleagues who do.  

Quote from @Leonard La Rocca III: So is it common to find a conventional loan without meeting the lender in-person?

In my opinion, an in person meetup > an online connection.You may want to consider making a connection here and meeting up for coffee or attending a real estate networking event.Best of luck!

@Nina Erlandson Personally, I have not heard of Obie Insurance.
