My adult children have 9 properties now ~ they advise me to buy a few rentals to provide eventual income supplementation after I retire. ( Who wants to be the retiree wiping tables at McDonald's ?

I do  have a good paying job that helps me pay my primary residence, but I like to plan for rainy days.My ultimate goal is have enough rental income to live off of, so I know conventional wisdom says I need to buy more rentals.

For me 5% or less is generally when I would not pay off early. 3.2% Do not pay that off early.  

Then I would verbally tell them after that that I will call the new landlord and tell them that you didnt pay rent . 

Can you use that 105K and invest in another deal to beat the $1,085 you pay for the mortgage?

The syndicator I worked for in the 80s he thought the grass was greener and went to Dallas bought used complex's and sure enough ( especially back then) new ones popped up, nicer units same price or a little lower and his tenants just moved across teh street leaving him with vacancies and out of compliance with the lender who then chose to foreclose as they did not have the cash to pay them off or lower the debt substantially. 

We didn't hear from her for 24 hours, so we sent her a reminder, and she said she would pay the next morning.

I would see how noisy it is from inside the house.You also have to worry about Families with smal children or pets.I would try and find something else.

With elderly tenants, good communication with their children can help prevent misunderstandings.

It took the buyer 30 years to pay off that mortgage.
