Also, in the Obama house picture - the house next door on the left has a bay window on the side. The white house has a bay window on the side. That house also has steps rising from street level.
Odd the Salvation Army white house address is 1305 Mercer when the front door faces 13th. The Park Manor directly across the street is #535 13th. Down from there is another white house (#521) and a green house from the same era but they don’t sit as high from the street. I can’t make out the address on the green house but the numbers do skip so they aren’t 521, 523, 525... Best guess is that the Obama house would have been across from the green house. That would place it in the middle of the block rather than the second house which the museum woman said.
Lot 9, now gone, was supposedly the location of the 516 property. It was NOT on the corner; it had a lot on either side of it according to the property record card.
Take a look at the large version of the old photo:

This is the front of the home. Do you see an entry door?
(good eye on the steps btw - you are correct imo)
