Mortgage Questions - Home Ready / Home Possible vs FHA

[Ada Li]

Hi there! 

1. What counts as income? Are bonuses included?
Home Ready and Home Possible have Avg Median Income limits (Philadelphia $84K)- I meet this requirement if I don't include bonuses (from referrals and performance so non-recurring) but won't if bonuses are counted.

2. Would it be less expensive for me to get an FHA loan or a Home Ready / Home Possible loan? Are there any calculators available? 
My understanding is what could potentially make the difference is the interest rate which is dependent on my credit score (which is 740+).

Any additional advice would be greatly appreciated (first time investor). Thank you in advance!
