I typically won't lend more than 70% of the purchase price or 80% of the repair cost...If you've got $50k, it sounds like you should be able to cover the remainder in a ~$150k deal...However, I also like for my borrower to have some cash in reserves in case things go awry...If the house ends up needing another $5k-10k for something unplanned, I prefer that the borrower not have to come back to me for more cash in order to get the deal done.

It sounds silly to think that your 27k rehab budget is going to run over by 10k.. that's an additional 37% of unplanned expenses, right?

I actually had not thought about that strategy of taking the 30-yr fixed option and paying it off like a 15-yr to allow room for any unplanned circumstances.

The high level risks are discovering unplanned repairs, anything that extends your timeline (since a decent part of your budget is holding costs), and problems with contractors.

LTV: 75% but let's use 70% as conservative estimate in case unplanned scenarios pop (i.e, appraisal comes in lower):Rehab: 25,000 Holding cost: 2,000Closing cost: 5,000HML cost: 45,000 * 10.5% = 4,725.

Hi folks, I've been studying the BRRRR method and would love to run this hypothetical analysis with you to make sure there's nothing I'm missing, especially with the added complexity with using a HML.POTENTIAL CONCERNS: I'm okay with the trade-off with less cash flow given my goals.I know it'll be a million times easier to go with the private lender route but I wanted to run numbers to see what it would look like using HML.I know it's going to very hard, maybe impossible to find anything with the purchase price so low but again, this is an experiment to make sure I understand how these numbers workREFINANCE / CASH FLOW ANALYSIS: https://www.biggerpockets.com/calculators/shared/593575/4c4d609b-475b-4c09-81a1-39f0280f291d ARV: 90,000NOI: 1,400Expenses (PITI + Repairs + Vacancy + CapEx + Utilities + Property Manager) : 1,300Cash flow: $100BUY + REHAB: Financing: I'll be using a HML that can finance 90% of acquisition and 90% of rehab. 10.5% interest rate on full note amount, 12 month term. 3% origination fee.LTV: 75% but let's use 70% as conservative estimate in case unplanned scenarios pop (i.e, appraisal comes in lower):Rehab: 25,000 Holding cost: 2,000Closing cost: 5,000HML cost: 45,000 * 10.5% = 4,725.

So you don't have to personally fix a leaky roof, but you do get stuck with the sometimes high COA fees or special assessments when an unplanned roof repair happens for the condo complex. 

Due to unplanned circumstances, I am also in need of income right away. 

I am planning to spend 5 hours a week educating myself, 3 hours a week networking, and then the rest is unplanned as of right now.

Any unplanned vacancy or big ticket item can punch a hole in your financial plans.
