Calculate basis in a 1031 exchange

[Jack B.]

I've seen a few different articles online about this with conflicting calculations but basically what is my basis for this 1031 exchange here:

-Bought a house for 63,240 paid in cash.

-Sold for 150K.

-After expenses my cash walking away from deal was 137K.

-I bought two new houses with the proceeds. One for 350K and another for 310K, 25% down each.

-I had to add about 28K cash to the deal for down payments on the two houses.

-Financing costs were about 10K approximately.

-Selling costs for the property were about 10K.

-I took 9K in depreciation.

I came up with 554,240 as my basis between the two replacement properties. Is this accurate?

I took the 63,240

subtracted 9K depreciation

subtracted 20K purchase and sale fees

added cash of 28K

added the 262K and 230K mortgages after down payment.

Per this example: https://apiexchange.com/replacement-property-calculation/

Taxpayer exchanges a relinquished property with a value of $1,000,000, mortgage of $500,000 and a basis of $500,000 for a replacement property with a value of $1,500,000, a mortgage of $900,000 and the taxpayer adds cash of $100,000. The basis is computed as follows:

Basis of Relinquished Property	$500,000
Plus: Liabilities Assumed by Taxpayer	+	$900,000
Plus: Amount of Cash Paid	+	$100,000
Less: Liabilities Assumed by Buyer	–	$500,000
Equals: Basis in Replacement Property	=	$1,000,000
