What book or credible resource would you recommend for me to read and or research?

I would either find a resourceful realtor and use them, or do research on how to offer on the land yourself.

The resources that Biggerpockets gives us for the 50 are so helpful to rookies, I know Puerto Rico is not a state but some help from BiggerPockets would be amazing.

That size would limit the number of life companies that would lend but there would be interest from a handful if the property is stable and in good condition.Freddie Mac also has a small balance program $1-$7.5M that would also be a good resource. 

I dont have to provide any accounting although tenants tried to tell me how to allocate the repairs.

Most investors that are securing such properties are leveraging  their business and resources to acquire off market deals, and are going direct to seller.

You can't just be new and say I can do everything because it's not just about producing leads, you still have to know how to close them and have the resources to do it.

I'd be happy to be a resource for you, I started off a few years ago and found a 4 unit that needed a lot of work and now have several properties.

@Vashon L HargroveOne of the most important qualifications you can pitch as agent who works with investors is that you are an investor yourself and have connections to resources such as contractors, lenders, and property managers.

I have been listening to podcasts, read, and subscribed to many of the different Bigger Pockets tools and resources.
