Joseph and Kendra Duggar have loads more on their mind than just their recent arrests — in calls obtained by TMZ, they speak about finances, taxes, and even potentially selling one of their investment properties to help Kendra out while Joseph remained in jail.

Listen to the audio — it’s taken from calls falling between March 22 and March 26 between Kendra and Joseph while he remained in police custody in Arkansas following his arrest for child molestation. They’re worried about cash flow and keeping Kendra afloat … but note that Jedd, Joseph’s brother, has stepped up to help manage their rental property, which is listed on Airbnb Guesty.

They even speak about getting a second property up and running to increase Kendra’s stream of income … but are also open to the idea of selling it down the road — or building a whole new pad with the help of a HELOC loan!

As you know, their finances are the least of the “19 Kids and Counting” stars’ problems — though it’s clearly on the top of their minds. Tontitown police in Arkansas arrested Joseph on a warrant out of Bay County, Fla., for charges of lewd and lascivious behavior – molestation of a victim less than 12 years old, and lewd and lascivious behavior conducted by a person 18 years or older.

And just 2 days later, he and Kendra were both charged with four counts each of second-degree endangering the welfare of a minor and second-degree false imprisonment. Kendra was booked into jail and released the same day after she paid a $1,470 bond.

TMZ has obtained numerous jail phone calls between the parents of 4 — including one in which Kendra said Joseph’s family is disappointed in him, but still loves him.

Joseph was extradited from Arkansas to Florida for his molestation charges and released Tuesday after he posted a $600k bond. The judge ordered him to stay away from his victim and not have unsupervised contact with any minor.
