By chance have you checked out the BiggerPockets property management finding tool on the website?

I totally agree and will say that I communicate proactively with my tenants and provide examples of the increasing costs of property taxes, insurance and repair costs (labor and materials).My theme to them is “we must raise rents to keep pace with rising costs, but we are doing the minimum increase as we want to retain you our valuable tenant”..

They have a lot of free info on their website as well. 

An example problem statement that I may have stated (and built the software for) in 2003, when I started investing full time: Build a tool for lead generation that collects county records from the county recorder's office (and property card data), finds the recent first mortgage defaults  from trustees websites or public filings for properties that are between 1000 and 1700 square feet, in a neighborhood of 90% like-kind properties with greater than 20 parcels, houses built after 1978, that can cash flow at current rates when fully leveraged. 

Also, check out out website easystreetcap.com to see testimonies from clients about their experience with us!

I would recommend attempting to obtain the contact phone number independent of the number that the tenant provides, i.e. website of the property.

My website needs to be updated but those are the homes I got from 2016 to 2019.

I also use a website called cozy.co to screen all of my potential tenants.

Just by googling 'buy a house in Nicaragua' I now found the cheapest SFH going for $44k on one of the brokers' websites, a lot of them in the hundreds of thousands USD.
