@Jordan MoorheadYes, an IRA is a mechanism to set aside a portion of your income and defer the taxes on that income.  

If this property is being sold to you as turnkey, if it were me, I would want to make sure the mechanicals will survive for another 5-7 years, that everything is up to code for that city/county/state, basically try to minimize huge capex in your first few years of ownership.

I would suggest you keep your first deal as simple as possible so you can gain some experience, like I did.This mechanism is easy to setup and any title company should be able to draft it for you.  

and at the end of the day, we need to be able to use common sense in getting into a door.Yes, you will need a WiFi set up to control the lock at your location and a very cheap subscription if you want to control the locks remotely -  but you don't have to.Beware of shiny, good "Apple" design looking products made of cheap and light plastics, especially when it comes to longevity and the heavy mechanics needed to withstand millions of physical movements and human force. 

To protect you from them not being able to finish the job, getting mechanic liens placed on your property, lawsuits if someone is injured on the job.

The key to good bookkeeping is knowing how to slot accounts or select the best account to enter the data in.It's not hard to learn so that you understand rather than trying to learn a mechanical process and then bump into some problem not knowing what to do with something that doesn't fit a format.I'd think Quickbooks would be good for the mechanical side. :)

Mechanical work allowed?

He knew mechanics and I knew paperwork; a good fit at a bad time.

For most HVAC related work, we design our buildings so that the mechanical closet can be serviced from a locked closet in the common area hallway.
