I am starting a park that will end up with roughly 20-25 lots on plot of land that's roughly 20 acres (including an existing 4/2 house).

At first I wanted to purchase a duplex as my first investment and was willing to house hack and rent out the other unit.

Additionally, I’m unclear on how their ARV analysis is conducted since most properties can be found on Redfin or Zillow — does it involve an in-person visit, or is it purely data-driven using comps and suggested repairs?

I'm moving out of my house hack soon and planning to rent half the units out long term and rent the other half out mid term.

The only way to get a standard conventional loan is with US credit, US tax returns etc...Unless you hold funds in a US Bank already and they gave you an in house loan or private loan based on assets.  

As of August 8, 2024, mortgage rates have fallen to their lowest levels since May 2023, sparking discussions about the potential impact on the housing market.1.

For me personally I did and do the latter land development and new construction along with all the entitlement work and horizontal then build new construction. 

If I buy these lots—7,500 square feet with a 50’ width—how comfortable can I be that the person who buys them from me will be allowed to build a house on them?

Personally, I would not invest in Nicaragua. 

House-hacking is way too trendy.
