<human>: Hi /r/personalfinance,

My parents are currently on a 7 year retirement plan, and while I am not aware of their entire financial situation I know that they plan on buying a house for 400k-500k and will be able to live comfortably for the rest of their life. As of right now, I believe they plan buying a house along the east coast, however have talked about buying a house in an area called Smith Mountain Lake (my mother wants to live here full time, my father doesn't) so more than likely if they had a lake house it would be a weekend/summer type deal. I don't believe they will be able to afford that without outside help from either my brother or I, and I would love to make this a reality for them.

Here are some quick bullet points about my financial situation:

* 26 year old male, making just under 65k a year

* 4k car loan as my only outstanding debt ( I could pay this off today, however use it as a credit builder)   

* I am currently throwing 3% into my 401k which is matched and then 24% into a roth 401k account which is not matched. Also maxing out roth IRA on a yearly basis. Total net worth of about 105k after 3 years of working

* 15k emergency fund (would last well over a year) and 17k in a separate account as savings, not currently adding to this. Plan on reducing retirement savings to add to this for future down payment on a house.

What are some things that I should be taking into consideration if I plan on helping them in the future? My plan as of now is maybe start putting some cash into an account on a monthly basis and go from there. I obviously see this as an investment as this house would be a family house and then eventually inherited by myself and younger brother, but I am not sure if I can swing having loan payments on two houses if I purchase a place close to me in the future.

Can you summarize the given text in a few sentences?
