Don't write off too much?

[Greg Baker]

I contacted a recommended mortgage banker at Bank of America.  I shared with her that my goal was to purchase my first buy and hold property within a year using Conventional financing, and then within 2-3 years, my family would be moving into a new primary family residence using another conventional loan.  My question to her was how will the purchase of the buy and hold impact my ability to finance a "new" family residence?  She said it should be no problem BUT do not write off too many expenses on the investment property.  She claimed underwriters do not like to see a lot of expenses written off as it shows I may be short on funds to fix issues on the investment property myself.  

Has anyone experienced this? Thanks!
