Undecided on wether it will be a multi family, duplex, or a single-family home.

Looking to partner with Experience team/developer for either single-family/townhome or high density multifamily.

My grandfather, along with his twin brother, were home builders who transitioned into building and managing a significant multi-family portfolio, which remains family managed to this day.With my personal family background, as an agent I have largely engaged in the multifamily space working with legacy owners in the sale of their properties - from 6 unit, single building properties to 19+ unit, multi-building properties.

All for a single property...It's a lot of work...for what kind of return?

If you are single then it is even easier.

That price for a cost segregation study is on the high end for a single family home 3.

Purchase price: $360,000 Cash invested: $40,000 Purchased this single family home last year.

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). 

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

@Gregory R Ley I would draft a letter to all 4 sets of tenants (so you are not singling anyone out) that clearly states what your noise policy will be going forward.
