Hard time getting a loan due to how little I make,Help for option

[Raymond Santos]

I am looking to get a loan and use about 5 different lenders (banks, and mortgage brokers) and they coming with too little of a loan for my purpose in the which is a duplex in New York City (queens/Bronx) . Range is 700k for duplexes in the area I’m trying to invest, looking and spacing out the area since is too expensive even the not great areas are above of what the loan officers are offering me. Any opinion or advice anything would help. I’m a new investor and just getting my feet wet and taking action. Also they gave me the option on getting a co-signer and that would help me get up to that amount or someone what close but I’m doing this by myself and have no one to help me do this.
