At some point, the scales will tip and then everyone left wants/needs to jump off in order not realize coming loses.It is a cycle, like most things in life, but one that can be avoided if you stick to what actually works rather than taking unnecessary risk just to force a deal.

It’s not unusual for a lease to end a week earlier than a typical monthly cycle, as this can accommodate a tenant's personal schedule or preferences.

The fight is business life cycle and unemployment.

One option you might try is to go to Bi- Weekly Payments, this way you collect on the same cycle as their paychecks.As long as both of your tenants still have their jobs, I would ride it out, the 2nd thing is how are they maintaining the property, are you going to have to spend thousands of dollars on repairs because of damage to the property.

I believe this market cycle is topping, and one should tread very carefully before investing more money into an 'unsure' property.That does NOT mean to stop investing; just make sure you aren't trying to catch a falling knife in an unsure environment. 

The question is: Do I let her rent longer, continuing to collect, then renovate before the next renters' cycle (around March/April or later)?

One hour in each direction of where you live will surely have similar opportunities and a much higher learning cycle for you.

It may be a difficult game to get into in 20 years, yet many will find a way and the cycle will continue, so long as the US is still standing.Ultimately, none of us has a crystal ball, we can only look at history.Conversations like these have been going on since the dawn of man and will continue. 

Just invested in deal #61 (25 have gone full cycle, so holding about 35).

IRA  Did the deal go full cycle?
