If a deal fits the criteria you are looking for, pull the trigger.

The landlord is locked in to the rate and terms specified for the duration of the lease.

So the lesson here, do your homework, and get it locked on the first meeting.Just my thoughts.Write your post

Reason being is that *one* of my goals is to buy and lock in at historically low rates as much real estate as I can that  fits my criteria; cash flow, low maintenance, desirable neighborhoods, etc.....

When an IRA that uses a non-recourse loan invests in real estate, it will trigger unrelated debt financed income; as a result, it may be best to perform such transaction under a solo 401k plan because a solo 401k generally is not subject to UDFI. 

I think this is going to trigger a taxable event for you even though it's tax deferred to them.

Should i pull the trigger? 

It locks you into the low payment, but anything extra you put towards the mortgage goes towards principle.

All of these tenants have leases that were inherited from the previous owners, or property manager depending on when they signed a lease.Some of these leases are month-to-month, some of these leases are extending out further through mid to end of 2017.My question is do I sign new leases and lock the tenants in for another year, and raise rents shortly thereafter, or do I just sign new leases with all of the tenants at the new raised rate?

The key is that after a certain amount of time, you have to be prepared to pull the trigger.
