I tend to categorize investors into 3 groups: Group 1: Too much deal flow and bandwidth but not enough money - (Lending is the key to this group's success/scalability)Group 2: Too much money and not enough deal flow - (All cash investing is the right decision). 

She told me just like this hire workers that do great work , have a timeline for the flip she said about 3 months is a good time another thing that I  found interesting if they don't get it done in that timeframe the lender charges them an extra 1500 each month until home is sold to get money back.

I know people that have spent money on courses and workshops, but personally I would rather put that money towards an investment.

I'm already migrating away from Quickbooks next year, so I will no longer be an Intuit customer for any of their products.There are several other options -YNAB, Empower/Personal Capital, Quicken Simplifi, Monarch Money, etc.

I just don't know if OC is too saturated with rentals for the summer and we would not bring in positive cash flow to make money off the rental.

@Eric Kahn Gale if the pipes aren't having pressure issues I would not spend any of your money replacing them!

My friend loaned someone money for a real estate deal. 

I have a few options:1) raise the rents without touching the property (cash flow could then be around 1,500$/month 2) update the units (estimated 50,000$) and then (cash flow around 3,000$/month)2) update the units and do medium term rentals (cash flow around 4,500-5,000$/month)I'm also having trouble kicking the current tenants out with how bad our housing situation is as well as homelessness.

(how much money you get back out).

Money well spent.
