The properties acquired during 2019 generated total revenues of $92.0 million and net income of $36.9 million during the year ended December 31, 2019.

The initial average cash lease yield for a property is generally computed as estimated contractual first year cash net operating income, which, in the case of a net leased property, is equal to the aggregate cash base rent for the first full year of each lease, divided by the total cost of the property. Since it is possible that a client could default on the payment of contractual rent, we cannot provide assurance that the actual return on the funds invested will remain at the percentages listed above.

In the case of a property under development or expansion, the contractual lease rate is generally fixed such that rent varies based on the actual total investment in order to provide a fixed rate of return. When the lease does not provide for a fixed rate of return on a property under development or expansion, the initial average cash lease yield is computed as follows: estimated cash net operating income (determined by the lease) for the first full year of each lease, divided by our projected total investment in the property, including land, construction and capitalized interest costs.

During 2020, we capitalized costs of $7.0 million on existing properties in our portfolio, consisting of $1.8 million for re-leasing costs, $198,000 for recurring capital expenditures and $5.0 million for non-recurring building improvements. In comparison, during 2019, we capitalized costs of $17.9 million on existing properties in our portfolio, consisting of $2.1 million for re-leasing costs, $801,000 for recurring capital expenditures and $15.0 million for non-recurring building improvements.

Of the $2.3 billion we invested during 2020, approximately $1.86 billion was used to acquire 127 properties with existing leases. In comparison, of the $3.7 billion we invested during 2019, approximately $2.72 billion was used to acquire 575 properties with existing leases. The value of the in-place and above-market leases is recorded to lease intangible assets, net on our consolidated balance sheets, and the value of the below-market leases is recorded to lease intangible liabilities, net on our consolidated balance sheets.

The values of the in-place leases are amortized as depreciation and amortization expense. The amounts amortized to expense for all of our in-place leases, for 2020, 2019, and 2018 were $134.6 million, $112.0 million, and $106.6 million, respectively.

The values of the above-market and below-market leases are amortized over the term of the respective leases, including any bargain renewal options, as an adjustment to rental revenue on our consolidated statements of income and comprehensive income. The amounts amortized as a net decrease to rental revenue for capitalized above-market and below-market leases for 2020, 2019, and 2018 were $30.9 million, $22.1 million, and $16.9 million, respectively. If a lease was to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be recorded to revenue or expense, as appropriate.

The following table presents the estimated impact during the next five years and thereafter related to the amortization of the above-market and below-market lease intangibles and the amortization of the in-place lease intangibles at December 31, 2020 (in thousands):
