Is it financially wise to pay my parents’ remaining mortgage which is only half of my salary in exchange for whole house to be promised via a trust and will?

However, I am living in another state for another year or 2 paying rent..though very cheap.

I must also pay property tax and house insurance in whole whenever they are due. The mortgage I’d be responsible for is 50k. The house is worth 900k. Property tax is about 5k each 6 months

Yes it does make a dent in how much money I bring home..and makes me close to living pay check to paycheck but I do have enough emergency fund for 6 months of rent at least.

All in all, is this a good investment?

Note: this question is assuming they will indeed put me on the trust/will.
