I do expect to have multiple properties and multiple partners down the road. 

When I have a common expense such as buying a tool (i.e. a lawn mover) that I use for multiple properties, how do I allocate the deductible expense to the multiple properties I own?

If you wanted to have multiple VAs able to call in and out underneath the call in number then you would set up a ringdown with multiple phone lines underneath the call in number.Ultimately I think you will spend a lot more money and have more difficulty finding a VA with a cell phone plan that is willing to let you forward an unknown amount of calls to them.

Or do we run a background check on multiple people that have submitted applications?

I have multiple HELOCs which I max out frequently as short term financing to acquire and rehab BRRRRs.

My plan is to replace my income of 100k per year over the next 5 years in multiple ways: as an investor and real estate investor agent. 

That's for my record keeping to know.I have found that online banks (Ally in specific) are pretty cool with opening multiple accounts for one owner. 

Be straight with all interested, explain there are multiple applicants and taking best and final by x date.

If I was to move on OOS investing I would certainly plan on multiple visits to the area while building a reliable team on the ground.I'm currently absorbing all of the information I can get my hands on, so i'm sure i'll be posting lots of questions.

One of them is to buy multiple income properties like Home and incomes and block of flats, these offer better returns.
