Remember that most things start to give you signs they are failing month or years before they actually "let go" so if you are often repairing a large expense item be wary and contribute more to your buffer.

In fact I have all of my properties in trusts which makes my residents a part owner in the property and they are required to take care of all the upkeep and repairs on the property.

Also, the repairs and vacancy that inevitably come with operating rentals mean a negative cash flow.Negative cash flow + low chance of appreciation = yikes.

However, I hope you budgeted in losing the existing tenant, repairs, and vacancy because any major increase of rent = this reaction.

So here are the numbers...House current value - $1 millionARV (every room needs updating) - $1.35-1.4 millionUpdate/Repair estimate retail finishes - $150KUpdate/repair estimate rental grade finishes - $30KThey both don't have money to update the home to sell for top dollar, so they are willing to take the $1 million and move on. 

Some are good with monthly phone calls, but not more frequent. 

When walking down the street you stick out like a sore thumb and the first person that sees you walks up to you trying to hustle you for money, borrow your phone, etc.

I rent out the spare bedrooms, which covers the mortgage, taxes, insurance, and repair reserve.

If I saw any signs of pipes, holes, or repairs to foundation I would get it scanned. 

If the property has any issues that would cause someone to not be able to live there (roof, plumbing, broken windows, holes in the walls, etc.) those items would come back subject to repair on an appraisal and need to be fixed before you can get any type of mortgage financing.
