Professional listing management and a buffer between the public/agents and the seller.

I think it would be wise to have an extra buffer, so if you usually buy at 70% ARV, maybe buy something like this at 60% or so. 

Data is showing 3-4% home value growth and rentgrowth of 7-8%.

I personally dont trust US government data.

I know data, and all the confirmation fallacy's and bias that can be concocted and "cooked" with data. 

There is a local REIA here that gets the Cromford report, so there must be free data here that's similar. 

Let’s be real…Most RE investors and wholesalers don’t have a (lack of) data problem.They have a data chaos problem.That was us.We were running a lean operation across a few TN markets, and like a lot of operators, we had a VA managing list pulls from your typical vendors, another one scrubbing and skip tracing, and 10 tabs open trying to keep everything current.What we really had?

Quote from @Edwin Varela: Where can I find consumer data about people (Americans) who are interested in buying properties in the Caribbean?

I’ve already pulled data based on the ZIP code (demographics, crime, rent trends, etc.), but I don’t want to base my entire decision just on that.For those of you experienced with LA or multifamily investments in general:What other strategies do you use to make sure you're not walking into a money pit or dealing with bad tenants from the start?

You’ll need to keep meticulous records of every payment received, send statements, ensure tax and insurance obligations are met, and possibly deal with late payments or disputes without a third-party buffer.
