Looking to do buy and hold  investing on small multi-family and single family homes where there is value add.

To answer your question: you should consult with an incorporation attorney to determine if single vs multiple LLCs are right for you as far as mitigating risk or other issues.Congratulations and I wish you nothing but success, Spencer.

If you can do it for a single family, you can do it for a duplex.

Too risky to trust your money to any automated system.The sales comparable approach to value will dominate regardless of cash flow if it's a single family home or 1-4 units and is being financed. 

I am looking at getting into rental properties both single and multi-family.

After that, I am undecided on multi vs single family, but have a feeling that multi will dominate, as I am always looking for bigger and better.

I'm surprised you can't find a single person who knows how a wholesale deal works. 

I am located in central Arkansas and plan on starting with single family homes to buy and hold.

I am going to start investing in single family and multi-family homes.

If I do a rehab and convert to a single family I could sell for around $280k-$320k.
