I focus on 1) making sure they have verifiable monthly income from a stable job that equals 4x monthly rent (gross income) + 2) no history of eviction (at all even 10 yrs ago is a show stopper for me) or recent judgements >$2000 (the concern is that they're going to get garnished eventually). 

My real estate goals are to eventually Buy and Hold as many properties as possible as well as developing .  

When block chain succeeds, crypto as Fiat eventually will too, otherwise there's little incentive for miners to mine.

We have numerous rental properties,  but since  it is a high end home, and eventually our own home  we have reservations.We have to make some decisions on this quickly to define financing and capture the rest of the peak rental season so quick feedback is appreciated. 

Unless the ground rent is unregistered (in which case the property may as well be fee simple -- nobody is going to register it now and attempt to collect on it, and you can eventually extinguish it as a matter of law), I don't see how it is possible to go through the closing process and not once be alerted to the existence of the ground rent.

It was inhabitable but I saw a lot of potential and eventually agreed to a $90k cash sale.

I eventually want to make it as passive/hands off as possible so wether its nearby or out of state I would need to get the right team in place. 

The differences in Building costs can vary so much, you may eventually want to get a commcercial contractor to estimate what they would charge to rebuild the structure as a backup.

ready for a potential downturn in the region you eventually move to.

The long-term play is to develop the land out eventually since it is a double lot zoned R-5 Multifamily and can hold up a 5-story multifamily building.
