I’m going to flip houses to supplement my income from being an agent and looking to use 100% of my flip profits to buy rental property.

This doesn't make sense to me because if you overspent on the rehab it doesn't sound like you will have much profit, so a rental might be the best way to salvage the situation.

If I use the contingency I still make a profit and I don't I have a nice bonus in the end. 3.

We've had the same tenants the last 18 months.Rent: $1,350/monthMortgage, Ins, taxes: $960/monthOur initial plan/goal was to acquire properties and hold them for long-term (20-30 years+) to essentially have the tenants pay for the mortgage and we would make a decent cash flow profit annually and then eventually have a solid asset (trying to diversify investing, e.g. not having everything in retirement accounts/stocks)Just recently the A/C had some leaks and is pretty much on it's last leg and needing a replacement (quote of ~$8-$9,000 installed + fixing leaks in duct work).

Sell 4 SFU3) Work with Developer to get whole deal financed, share more of profits.

Income wise, 2017 was 6 figures after all expenses. 2018 isn't bad so far but I'm pissed about 2 deals that I almost had which were about 60k profit combined, in one month.

We agreed he will received principal + % of profit in return after the flip.

Figure out the realities of TODAY to bring the project to completion and still make a nice profit. 

As I continue learning about REI, what I'm thinking more and more is that what is maybe the single biggest factor in profitable investing is given surprisingy little attention.

35-40% non refundable is insane unless the potential profit is overnight 10x.
