Buyin 1st primary res.- buying starter home VS house to grow into

[Robert T.]

So as the title states,  what're some opinions when it comes to buying a starter home, below budget, VS buying 4 bedroom home that may stretch budget 40% of post tax income.

Reason being and things I see, buying a starter house..living in it for 5 years, only paying off interest, and then moving again.  So why not buy a primary that I know I can and will grow into with the serious girlfriend.  May stretch now, but with dual income it becomes extremely affordable.  No moving, relocating, and buying a house that don't need anything major for ~10 years is great vs coming in below budget and I have to do a roof year after next.
