You're best bet is to call a local multifamily broker.

Ocean lakes in Myrtle is probably your best bet. 350k may get you a 3/2 which will gross around 45k per year. 2-3 years ago you could pick up a 4/4 or 5/3 for that price so you may be priced out but there are a ton of condos for that price of 350k although I wouldn't buy a condo there we have two 4/4's but we stole them before pricing went crazy here in ocean lakes.if your diligent you can still find a deal but is much harder now 

Here's what I've observed: in the areas with the best growth potential (for both rents and appreciation), existing small multifamily is very scarce.

Selling can unlock equity for a larger building, offering diversification and potential higher returns, especially in the current strong market.

Big difference in time commitment, risk, and potential profits 

Both have their own unique advantages and can offer great potential for real estate investing.

Appreciation potential certainly may be there but are you ok with neutral or negative cash flow?

Factors like zoning regulations, property size, and potential impact on your primary residence need to be considered.The ADU process can take time.

SFR is probably the best bet for this group of buyers.

Also I have the potential to buy the neighbors lot of another acre guessing I could get it for $300-400k.
