or even better is there some tricks to set up quickbook with one account but handling all these companies?

In fact the properties I bought here specifically for cash flow (multi families in mediocre locations) did not end up performing as well as my other properties over all, so I sold them and put that money into more properties with less upfront cashflow on paper but better overall returns. 

Instead, I’d look for:Lower-priced properties in better cash flow marketsA better rent-to-price ratio (aim for 1% or close to it)Creative financing options—seller financing or an assumable loan with a lower rate could make the numbers workIf your main goal is long-term appreciation, make sure you’re okay covering that monthly loss for years.

You get the best of both worlds in that way: No seasoning to pull cash out AND the conventional rate/costs and no pre-payment penalty which are all better then DSCR loans.

Once you do deals you'll be able to estimate better and it's faster.

You get the same FHA benefit and have a better economy of scale renting 3 units instead of 1.

However, short-term strategies like value-add flips, BRRRR, or even mid-term rentals might offer better returns in certain markets.

For anything investment related your  better off using an insurance broker opposed to using a Allstate or State farm.I am happy to refer you to my guy - he's great and gets some amazing rates!

Consider a home equity loan or HELOC to tap into your condo’s value while improving your credit score to qualify for better mortgage rates.

This gives much better diversification protection across geographies, asset types, strategies, investment subclasses etc. versus putting all the eggs into one basket.The downside is that it's not for everyone, and a person has to be comfortable with turning over control to someone else.
