First time investor help

[Wesley Robirds]

I'm looking into my first potential investment, I'm looking for any ideas of possible ways to get the capital the list price $550,000 on four units, current rental income $3595/month the property is in good shape has two long term tenants and the other two unit are occupied and I'm currently looking into financing but I don't think I'm going to be able to get a conventional loan any ideas on other possible ways to get the funds that perhaps others have used or know of I'm brand new to all this and I'm still learning a lot. Thank you in advance
