It could be a serious issue for your later home-buying--and otherwise:1) Even if your mother is in fact paying, if the homes are in your name, you are the one whom lenders will believe are legally responsible for taxes, utilities, maintenance, etc.--you will appear to have a number of obligations, which will reduce your credit-worthiness.2) It looks suspicious for someone to have multiple homes bought for cash if they don't themselves have the assets to do this: it may make lenders (or the authorities, if reported to them) think you are laundering money, and refuse to lend or even investigate you.3) If you mother is already remarried, in the event of a divorce, this will look like exactly what it is: an attempt by her to hide assets from her husband. Not only will it very possibly fail, you will be dragged into her divorce.4) If someone is injured at the home (e.g. a slip and fall) you, as the person on the title, could be liable.Don't get involved in your mother's finances or schemes; let her handle her own property herself.
