Investing in a single-family home in LA and expecting a good cash-on-cash return will be very difficult. 

The newest outdoor is still advertising 1st month free as they haven't filled up, and I spoke with the climate controlled owner/builder yesterday (he's a pretty big REI in the area), and he made it sound like he hadn't leased a single climate controlled unit since they opened a few weeks ago.I recently purchased a 140x45 warehouse with low ceilings and had debated doing self storage, but my market seems very saturated.

I have 2 single fam homes, but want 5-10.

There are 4 Single Family Homes built on the site. 2 are built-to-sell and 2 are built-to-rent.What made you interested in investing in this type of deal?

Instead of moving into another single-family home, consider house hacking a duplex or triplex, this allows you to use low down payment loans (FHA, conventional) and offset your mortgage with rental income, accelerating your path to financial freedom.

And I’d like to build the single family home and refinance with a dscr loan.would anyone have any advice on this or suggestions 

I was more interested in Fix and Flips or maybe even rentals for single family properties.
