Thanks everyone for the replies. That's very helpful.
So this conventional loan does not have any primary residence requirement, according to the loan officer. The lender said that only the first conventional loan can be with 3% down, and after that it would be with 20% down. There is a requirement for that loan, which is to not own a house before getting the loan. Meaning, if I get a house on FHA loan, I would no longer be able to get the 3% down conventional loan.
So the approach I was thinking to do is to purchase a rental house with the 3% down conventional loan first, then purchase right away another house with FHA loan for me to live in. How smooth would that be? An important question that pops up is: can I get FHA loan right after purchasing a house on a non-FHA loan? Is there a requirement for FHA loan that I haven't purchased a property recently?
As of being able to afford paying both mortgages and expenses for the long term, I was thinking that the first house on conventional loan would be rental, and the rent would cover all the payments and expenses. In that case, would that be excluded from my DTI ratio?
It's very exciting if I can make this work out.
Thank you,
