Bingo!
Your home is the 4th. Uranus is sitting there, who just happens to rule your 2nd of money, so that is where you money is going.
The ruler of the 4th is Venus, who just happens to be inconjunct Bilk in the first house, you!
So it's all becoming clearer.
So where is Venus? On the cusp of HER 4th, so it isn't her mother, it's her house!
Also, Bilk is very close in the first house to Veritas, who sextiles Neptune (in her 12th).
So Bilk is cleverly blending itself with Veritas, Neptune weaving its web of deception, presented to the ascendent, you. Part of her story is true, if I recall correctly, in that her mother has a health problem? The best lies are those with some connection to the truth.
And finally, your neighbour is the 3rd house, so her money 2nd is.... your 4th!
So that's what it's all about !
