I also invest in single family and small multi family properties with my husband, a NYC based general contractor with a focus on residential renovations of town homes, apartment combinations and out of the ground houses.

I focused more on the single family homes than multi family at the beginning.Its okay to start with turn key options, but if you are just starting out - you will need to figure out all the steps first.

It may pencil out if you're building an extra unit, but just a single bedroom is not going to work.

Quote from @Terra Padgett: If I had $1M to invest in real estate, I would ______. build ground up single family with half and ground up 3 units with half. allocate 500k for each venture in one city where economics are favorable for build to rent 

How about evaluation single family or residential properties?

Is this a single-family home or a multi-unit? 

I wanted to see if anyone is familiar with or can recommend paid mentorship programs or coaches for small multifamily unit investing (2-4 units).In my research, I’ve found that most mentorship programs or resources I come across are geared toward large syndication apartment building purchases or other types of investments, such as short-term rentals, medium-term rentals, single-family homes, Section 8, or fix-and-flip projects.

As big as you are, you should consider moving the properties into multiple LLCs (my personal rule is no more than $1M in single familys in one LLC, but this may need to be higher in your area). 

Elk Grove is growing and has been/continues to be good.For appreciation, single family have been better than multi though.

And since I am beginning I am looking for single family.
