No, I'm not a visa officer. Probably a good thing that I'm not the visa officer who will be evaluating your mom's application
Regarding the cash deposits/transactions:
The visa officer will question these transactions. It seems like there are only inward remittances, probably 4-5 transactions a month. So, it's not hard work to figure out the bank transactions.
1. Is your mom's visit urgent? Can she apply for a summer trip instead?
2. Applying for a summer visit would give her time to sort out the bank transactions. For example, have the rent credited as checks and not as cash.
3. If you intend to apply for PR, I would recommend you apply for a super visa instead. Your mom will have a better chance at a super visa approval
