Best way to get investment loan without effecting credit score ?

[Anthu Tam]

Hi, I am a newbie to property investment who purchased a secondary home and a investment property using the same lender within  a few months timeframe. I see this effecting my credit score heavily. Is there a better option to obtain loan without effecting credit scores? Should i wait longer before i purchase a investment property like an year between each ? Or should i use a different approach without taking a loan ?
