People simply won't easily buy a house with previous hystory of crumbling foundation even if it is fixed... or "claimed" to be fixed.The 70% rule also doesn't account for the projected time it takes to flip a house.And no... your predetermined "holding cost" incorporated in your 70% rule is not it.The 70% rule is a death trap and is a sure way to derail your business.Also, if we are both interested in the same property, and you give a 70% offer, you will ALWAYS be beat by me that will ACTUALLY give the highest possible offer I can make. 70% rule focuses on being "safe" and will have the effect of not getting many deals.The right method focuses on property determined risk analysis to leverage "being safe" with the amount of allowable profit (for that safety margin). 

Then later down the road, to the BRRRR method and get another property!

You can also ask her what her expectations are and her preferred method of communication.

It'll get to market rent eventually, was more interested in a good relationship and no turn over)Submitted my rent increase and paperwork to section 8 (not real hard) Rent Increase was approvedNormally I would do a nice rehab..but it already had a paying tenant and was in "good enough" condition.My hopes were that it would appraise $100k+ and worst worst case a little higher than purchase price ,which, even then my ROI would be very high.Fast Forward 6 months...Appraisal comes in at $102kThrough the cash out refinance and 6 months of cash flow this was an infinite ROI deal as it put every penny back in my pocket (plus more) through a more unorthodox "sweat equity" method of buying a low demand, poorly marketing property with barriers to entry..

I am sticking to the enemy method.

Slow and methodical approaches will gain the most ROI

Do I still need to still have the parties involved served the judgment even if I choose to use the collection agency method you described?

@Dave ToelkesCalculations based on your above assessed value method work out to be ~110K and 73K.

Then quit your job, and keep recycling through the LOC to fund rehabs, either flipping or through the BRRR method.

I thought this was the method that most flippers used?
