They should be able to introduce you to the rest of their team/network.

@Manny CirinoHi, I did some research, single family house can rent out around 1,400 to 1,500 a month, tenant will pay all utilities, i plan to put down 50k cash, borrow the rest, estimated payment is about 800 (5.7% interest + tax + insurance).

One unit has mixed personal and rental use in 2019 and the rest is 100% rental.

However from my research I've learned many investors suggest calling 3-5 contractors and requesting clear quotes. 3 people could give you a good expected range, however 5 may let you throw out the outliers at the top and bottom (really cheap), then choose from the rest after calling and checking references!

We have officially started the company as of this month.

You might consider installing a gas fireplace where the furnace is, (you all ready have all the connections there) and use the baseboard heat for the rest of the house.

I will pay the rest out of pocket to live in the main house.My home value: $325kMy equity: $100kMy home on Airbnb: $30k+ (AirDNA says $43k, so should cash flow easily)Why would the HELOC be better than a cash-out refi when I can lock I  interest rates as low as they are now?

When you do it this way you can take the full $500K tax free and do a 1031 exchange on the rest to purchase a property that is either adjacent to your retirement home or could become your retirement home after a while, or is a nice vacation investment to give you a break from your retirement home when needed.Second, the rentals. 

After you make your offer and get it under contract, then you get the official inspection done.

Then use the rest as a down payment on the BRRRR fix n flip loan.
