Not sure if it was mentioned here already, but another creative alternative is to purchase a SFH that has a casita. 

Hi Evan from Sayville, NY-You asked about whether a lender would pay real estate commissions and closing costs with a short sale.I negotiated a lot of short sales after the Great Financial Crisis.Short sales are similar to dealing with a bank owned property accept the bank is trying to avoid taking it back so the terms, specifically an acceptable purchase price, have to be negotiated.The thing I found that was important to negotiate was the lender agreeing to settle without further recourse for the seller.

We would prefer to jump into the market with a duplex, triplex or quad as our first purchase. 

I purchased my first investment property through an online auction for delinquent property tax.

Purchase price: $516,000 Cash invested: $600,000 Converted mixed-use 3 residential and large commercial space into 5 residential units and one mixed-use Building.

In about one year, we intend to make our second real estate purchase, which will be a more permanent home for us.

I have an opportunity to purchase a duplex property walking distance to a SUNY University. 

Purchase price: $325,000 Cash invested: $2,485 Sale price: $335,000 Low upfront cost due to creative financing.

Purchase price: $137,500 ($44,000 in to the property... loan at $101,000)Appraisal: $180,000   ARV: $195,000Est rehab cost: $7,500Scenario #1: 75% LTV cash out refi at 4.25%...

I think the Air BNB numbers work compared to the purchase price of some of these homes.
