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.

It simply says she lived below her means and invested for the long term.   

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.
