What are the issues with buying condominiums for rental income?

I'm new to investing and wanted to see if condo's or town houses would be the best place to get my feet wet. I'm looking to buy and hold and looking for cash flow. I know these type of properties don't appreciate like...

A B&B doesn't sound like a residence but the California Legislature and courts have ruled that "...the Act has been held to apply to operators of motels and hotels; real estate brokers and agents and others engaged in the sale or rental of real property; owners of triplexes, duplexes, non-owner occupied single-family dwellings, and publicly-assisted housing projects; operators of mobile home parks; and condominium homeowners' associations."

If the the investment is 2-4 units, generally 40% of IRA funds is required.If the the investment is condominium, generally 40% of IRA funds is required.If the the investment is multifamily, generally 40% of IRA funds are required.Typical Loan Terms Available from Banks Specializing in IRA and solo 401k Non-recourse Loans-5year ARM-10 year fixed-20 year fixed-25 year fixed-$50,000 to $55,000 minimum loan amount is the common figure.

Ellis evictions are used to convert rental units to condominiums, using loopholes in the condo law.

I thought of creating a condominium association for the 2 living spaces and selling those and keeping the 2 commercial spaces. 

I have 4 units of one bedroom condominiums all located on the same complex. 

I have recently purchased a condominium as my primary residence in August 2018.

I was first introduced to property management when my boss promoted me from Executive Toilet Cleaner to Assistant Condominium Manager.

Recently i sold a condominium with sinkhole in the property in Tampa and I had all disclosures and engineering report Attached to the listing (I represented the seller) and sold it without any problems for the buyer.
