Typically, big banks such as WellsFargo, Chase, etc are subject to following Fredie mac Fannie Mae guidelines. What this means is most big banks don't like to lend over 4 properties, but Fannie Mae guidelines won't allow them to lend over 10 properties.
My suggestion would be to search your local area for a "portfolio lender". A portfolio lender is just a fancy term for a bank that doesn't sell off the mortgages they originate. They lend there own money and keep the loans in house, so this means they aren't subject to following Fannie Mae guide lines. They tend to have much more lenient lending requirement, more creative with lending abilities, and investor friendly.
Now if you want to find a portfolio lender look for small local banks maybe 1-10 location in your area. Call them up ask if they are a portfolio lender. The person you talk to probably won't be familiar with that terminology, so then ask if they sell their loans off or do they keep them in house.
I would consider looking at residential multi family (2-4 unites). The reason being they are still considered residential properties, meaning you can qualify for an FHA loan 3.5% down.
Also, the economies of scale will make things much more smooth. It's much easier to manage 4 units on one property than 4 different houses in 4 different locations. You also reduce your risk with vacancies. If a tenant in a SFR moves out your 100% vacant leaving you to pay the mortgage by yourself! If you own a 4-plex instead and a tenant moves out you still have 3 other tenants paying the mortgage.
If your interested in multi-family the best book to read is:
"Investing in Duplexes, tri-plexes, & Quads by Larry B. Loftis" AMAZING BOOK!
Also, if you like podcasts Youtube. "Grant Cardone" & "MFCEO Project"
Best of Luck!
