Over the past several years I've tried to educate myself on the logistics of buying and managing a house as an investment and attempted to learn from other peoples experiences in REI.

i was told by a few people on bigger pockets and bank manager assume , not the amount you need but enough to help if you got money on your own to add,

We also have zero RE investing experience, so we would be also be the much safer and easier option than having to manage a long-term rental. 

Are you working with a property management company or trying to do this yourself from afar?

It will emphasize the role of investors, developers, and property managers in driving the transition towards more sustainable practices and the collective benefits of these efforts for the planet and future generations.

Your "Core 4"(Realtor, Property manager, Contractor, Lender) are all critical to your success. 

Study the markets you are targeting and find investors/agents/property managers in those areas to network with.
