Hello BP,
I am very interested in real estate investing and have read david greenes BRRRR and Long distance real estate invest. Have also been doing lots of research on the side, but I don't know anyone to talk real ...

I don't know your relationship with this renter either as I think that will dictate much of your next steps here..Since they left you (the homeowner) out of the process of replacing a key feature of the property's form and functionality, I think I would require them to pay for a 3rd party inspection to properly assess the install and make sure it's what you need.

Cap rate is the ratio of net operating income over the property value.It is not a function of the financing rate used to acquire a property.It is a good tool to compare various commercial assets just based on the cashflows those assets produce and the asking price or market value they command.For that reason there is no direct relationship between cap rates and interest rates.It is more of an indirect one.

I assume it would take years to sell them all off    :/A wholesale or partnership with a developer is not a bad idea. 

It’s also a way of showing we’re serious on closing deals and in this partnership.

This can be stock, partnership interest, or business property.

LLC: Making that call will depend on personal factors like your income, tax situation, partnership/membership issues, and much more than anyone can ethically go into detail with you on this forum.

Everyone here has been so helpful and I look forward to many partnerships with bigger pockets members.
