What is the difference between Vた + つもりで and V-る + つもりで?


I understand that the construction Aつもりで means "with the intention of doing
A". However, I've seen in several fonts that when A is a verb, it can be both
in the た form or the dictionary (る) form. I've also asked a native Japanese
person about it, but she couldn't explain the difference to me, but rather
just confirm that in some example sentences I have, only one of the
possibilities makes sense. So there must be a difference. The examples are:

> ○ 父は家を **建てるつもりで** 、土地を買いました。

> ✕ 父は家を **建てたつもりで** 、土地を買いました。

"My father bought a piece of land with the intention of building a house."

> ○ 旅行に **行ったつもりで** お金を貯めている。

> ○ 旅行に **行くつもりで** お金を貯めている。

"Saving money with the intention of going on a trip."

I think that [this answer](https://japanese.stackexchange.com/a/48074/32952)
is related to my problem, but I can't make sense of "with imagination as if
you had bought it", either.

Thank you in advance!




I think your understanding - "with the intention of doing A" is for Vるつもりで.

I can think 2 ways to use 'Vたつもりで'...

1 - "pretending having done V" もう勝ったつもりでたたかう。 fight as if you have won already

2 - "having done V (but not necessarily completed at the satisfactory
standard)"

ここに鍵をおいたつもりだけど、見つからない。 I put my key here but I can't find it. (I think I put
the key here but am not sure if I really did)

有名になったつもりですか？ Do you think you became famous? (but you are really not)

I hope this helps!
