Hi Ricardo,
I'm in the Reno area as well and had a similar issue regarding what I could qualify for based on income. Hakeem is definitely right about contacting as many banks as it takes to find one that will work with you. They're going to look at your debt-to-income ratio and the right one will also take into account the projected rents. It will help to present to potential lenders showing what your deal looks like with all of the numbers and BP calculators should do the trick.
If the unit needs any work done, you may consider using private money to flip it and refinance out of the short-term/higher-rate loan. There are a few in town I could recommend. Personally, I am partnering with a friend since he has money for a down payment and I have local knowledge/sweat equity to contribute. In general, though, look at local lenders that may be more willing to work with you than some of the bigger national ones. Sometimes it can even depend on the specific person you work with in an organization who wants to help make your deal happen.
Do a simple Google search for "Northern Nevada mortgage lenders" and make sure to look at local options such as Greater Nevada Credit Union, Bay Area Equity, etc. A couple lenders I know personally are Desiree LeBleu at PrimeLending, Ron Moschetti at Summit Finding.
Best of luck in your search! Feel free to connect as I'm just getting started in the area too with my first house hack.
