All in all, everything I analyze from wholesalers, independent and large, are only giving about a $20,000 profit.

The goal is to make money, collect profits, NOT collecting properties.  

(I am a silent investor, the developer is doing all the heavy lifting, and we split profits at the end)

Then turn your profits into assets that provide monthly cash flow.

Now that I've had a bit of time to put in some info into rental hero, under the "profit and loss" section, you can save/print a PDF with details. 

How are you more efficient, and how on earth will you possibly make a profit charging only .60%?

Either1) your startup takes off and you can distribute profit fast enough to pay off your debts, or2) you find another source of $100,000 a year (which barely even starts to pay down the $300k, but might provide a better chance for a better loan), or3) you BK and possibly lose the rental houses to creditors (hopefully not, but we don’t know how they are held), or 4) you sell the houses, take the tax hit, work with the IRS on a payment plan whose interest will be much lower than your CCs, and focus on the startup.  

Just make sure the cost of your protection doesn't rob your profit. 

@Yezenia HernandezI started with pre-construction short-term rentals in the Riviera Maya, since it's Mexico's and one of the world's main tourist destinations and so the profitability has been very high there.

I'm making great profits off them, but I'm having issues with my m-th bookings and I would like to raise my rates.
