Remember Maslows hierarchy of needs: humans always seek to avoid pain 1st.

Petty theft is common here, elsewhere in Costa Rica, and probably anywhere else human beings live. 

We believe this property is a great guinea pig for the ADU add as there is so much value being added with the second primary that it leaves a ton of room in case the ADU doesn't get the appraisal we need. 

If there is a way to over complicate things us humans will do it 1 go to a bank ask them to prequalify you 2 contact a couple real estate agents in the area you want to invest in.

When choosing an agent make sure they can provide you with as much value as humanly possible! 

Also, anything working and reusable like appliances, ceiling fans, cabinets, sinks, doors, etc can be set aside and once you have it out Habitat for Humanity will send a truck and pick it up for you as long as you have big items and a local store.

Get over your fears, treat people like humans, and start to have some conversations.
