Here is a summary of the book.https://www.nateliason.com/notes/long-distance-real-estate-investing-david-greeneThe book also mentions the importance of having a rockstar Realtor, contractor, lender, and property manager.

Many private/hard money lenders partner with passive investors to help fund their loans.   

Cash is fast.Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

We check public records BEFORE calling landlords, so we can trip up fraudsters!

I'm not sure if any local lenders will consider the property value once the ADU is complete when reviewing my loan application.

Explore your financing options, such as traditional mortgages, hard money loans, or private lenders.

Make sure to connect with local lenders and brokers as it's beneficial for achieving your real estate goals.

I also have a list of lenders that I have worked with in the past that I recommend.In both cases, when I was approached by them to purchase a home, they had very little knowledge of the home buying process, they were definitely not ready.

We had no credit history in the US so most typical lenders wouldn't work.

Following David Green's Core 4 strategy (realtor, contractor, property manager, and lender) gives confidence to invest anywhere.
