I would particularly love to help someone within the Atlanta area with a fixer-upper by providing some physical labor.

If the guest feels slighted, there is no fact checking service provided by AirBnB to confirm their claims, so it is up to you to let future guests know the level of professionalism you provide.If you are able, I would recommend editing your response to the 1-star review.

This is my first deal and I wanted something to provide me stability for future me

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

No but you could create an excel macro to do multiple properties at once - also the numbers that someone provides to me I take with a grain of salt anyways. 

Hi to everyone,I would like to ask that ,my banks in my country (Greece) are unable to provide refinance options for the BRRRR method (Buy, Rehab, Rent, Refinance, Repeat), what alternative realistic strategies can I consider for implementing this investment approach?

They do this by the Scope of Work with Budget being provided to them. 

If you die while holding the property, it gets a stepped up value and all the gain is tax free.If rental the taxes can be deferred via a 1031 and if you die while holding it, it gets the stepped up bases with gain forgiven.Hopefully the numbers provide some example of possibilities. 

We have both always been interested in forming some partnership in which I do the leg-work and he provides the finances.
