Plano Texas Home Buyer Questions

[Joshua Davidson]

Looking at buying a house in the Plano Texas area. Realtor is encouraging us to purchase a house 2000 or newer. Realtor is saying that homes built before 2000 will cost us up to $300 more in electricity bills. Is there truth to this?

If I am looking at a house Pre-2000 what should I consider regarding the electricity bills question above and any other recommendations?

Can you recommend foundation considerations? What are the pros/cons of post-tension foundations?

Thank you
