However, the BRRRR method is a great strategy for speeding things up a bit and assuring that you can continue to scale as you find properties that pique your interest. 

He will remember this was one of the best opportunities he took looking back and I aim to assure I help him in his success in placing tenants and guidance learning how to run the rehab and assist with my resources.Check my profile out as Ive mastered the BRRR strategy and help others with the experience I've gained along my journey.

Now, once the money is in hand and the purchase has gone through, how can I assure the lender will get his or her money back on top of their charged interest in their requested period of time (6 months-5 years) and, at the same time make sure I am cash flowing at a number that makes sense to me and my investment.     

I can assure you that my tenants are ONLY interested in seeing the current month due.

The realtor I'm getting this information from told me that the property comes with a Warranty Deed and assures me that there are no obstacles.

The reason that a Quit Claim deed may be sufficient to transfer your interest into your entity (as opposed to using a Warranty or Grant Deed) is that you don't need to assure yourself marketable title; you already have that.You could see a lengthy discussion on this thread about strategies and tactics concerning methods of holding title.

Rest assured that there WILL come a time when you will disagree.

I bet you solve most of this by a quick boilerplate paragraph on the app about how you keep the data secureI wouldn't even do that, it conveys liability which most can't assure.

If not a seasoned pro at doing long distance flip it's all but assured the budget will be blown in some way shape or form, so probably more like $40k or $45k to gain $15k or $10k, or worse.

@Preston BrownWhen a vendor, or her/his agent, are advertising a property for sale, rest assured they will paint the rosiest picture possible.If they are advertising Rental Income of $1200.00, it would be safe to assume they are talking about "scheduled rent" - the income they would receive if the property were 100% full, 100% of the time at the posted rent rate(s) with no economic vacancy {tenants not paying, evictions, etc.} or loss to lease {move in incentives such as 1-month free rent}.
