Once your emergency account has a reasonable amount in it, whatever that means to you, you might want to think about steering that payroll money into the investment savings account from each pay check and leave the emergency account money as is.

If you have a chunk of money to get going I'd personally buy the biggest thing you can if you don't I think house hacking into a 4 plex is great. 

Going direct instead of having a GC do the work will save you money too since that GC will put a percentage on top of work. 

I would like to put the money into purchasing another investment property.

They reversed the transaction initiated by the hacker and I can withdraw the money from my account.

You have zero control over the stock market, whereas when you do private lending, you have significantly higher control and contractually guaranteed return on your money.

However, there are other loans designed for fixer uppers referred to us hard money loans, bridge loans, or fix and flip loans but whatever you want to call them they're essentially short term, interest only loans with no prepayment penalties designed to finance a higher % of your purchase price and typically all of your renovations not to exceed a certain % of the ARV (typically 75% max). 

Hard Money How did you add value to the deal?

How much money is paid to GP’s for work done?

@Pranita Maldikar Unless the seller is a family member or personal friend, I'm not sure why you'd want to put that much money down on the property.
