Looking for someone who charges a flat rate per deal and willing to help while I learn how to write up contracts etc.TIA!

The rental income of this California would be ~$4k/month which only covers existing mortgage and property taxes, therefore much better ROI for cash flow elsewhere assuming that appreciation would remain flat for the next few years.My limited understanding:1.

They also offer install for a flat fee $75/cabinet, which allows them to remove sales tax from the equation since they're now offering a service and not just a product (or something like that). 

Charge a flat rate utilities fee for each unit and roll it into the rent and set up a contingency fund for potential months where the solar array doesn’t produce enough to cover the entire energy needs of the home .( this method appears to be potentially profitable.

While the "city" is staying flat in terms of property values the suburbs have been appreciating. 

For some reason I thought it was 8lots because of the new meter panel that I’ve install is a 400amp service and the electrician told me anything pass 400amp is commercial, newbie mistake I didn’t verify so I went with it and with that system I can put up to 8 lots total(2existing and 6working-on).

And the capital gain tax is a flat tax that is calculated separate from your ordinary income. 

Out of curiosity, how is the overall terrain around your neighborhood (very flat, hilly, etc)? 

If I had to pay the panels off which is still around $20,000 it would make this house not a deal.

Once the "ball" is rolling (you start getting rental income to offset your debt payments) your DTI stays fairly flat as you scale, but if you buy a single family at $400k and then want to invest, it will be a much slower process.
