Also to focus on actual B-class pockets, I would also suggest extracting data by crime statistics, median household income and school ratings.

A few things to consider:Owner-occupied seasoning rules may limit how much equity you can extract at refinance, depending on lender overlays and market appreciation vs. forced appreciation.If the goal is to accelerate, some investors bridge the first acquisition with short-term capital and refinance into DSCR once stabilized — but that requires tight underwriting and liquidity discipline.The biggest risk in BRRRR cycles isn’t the rehab — it’s misaligning timeline, refinance eligibility, and capital reserves.If you model those three variables conservatively, the strategy becomes much more predictable.

The markets where this might not happen are higher risk, typically historically shrinking markets often class c or below.Let’s say you buy a class b right n a non-shrinking market, rehab it right, get your high LTV refi to extract all, or nearly all, of your initial investment you likely (virtually certainly with  accurate projection on vacancy and sustained expenses) will have negative cash flow property using traditional LTR.   

I keep running into the same operational headaches across my own properties and seeing the same issues with clients - 1099 scrambles every January, missed lease escalations, surprise capital expenses, insurance renewals that sneak up on you.What I'm thinking about building:A platform that automates the tracking of all this stuff:AI extracts lease terms from PDFs (no more manual entry)Tracks vendor payments and flags 1099 requirements automaticallyAlerts for insurance renewals at 90/60/30 days outMonitors capital asset lifecycles - know your HVAC is 18 years old before it diesAutomates CAM reconciliation calculationsIntegrates with bookkeeping/financial planningWhat I need to know:Are these actually widespread pain points or niche problems?

Analyze your market, how you can add value, extract other extrinsic points then appropriately allocate capital and manage the risk for the portfolio.

It is a mathematical certainty that a higher rent growth market will eventually have the better cash flow if no extraction of value and all other expense related item rise similarly.

It's a term game - and I think I've extracted the 80/20 of appreciation on my current home and I'm looking to take the gains and apply it to something with better cash flows and more upside on appreciation, as well as a fun place for me and my family to vacation, cost free (even if it never rents, we still own a vacation home with no mortgage). 

You're not going to see much cash flow on these (if any, sometimes) but your return is in the asset appreciation, and the ability to extract cash from them, for life, to buy more assets- cashflow - these are homes in markets that have the economics to support this goal.

I believe the reasons were two, one to maximally keep extracting funds from us and to keep hidden, according to the judgements against them, the massive fraud perpetrated by them.  

The numbers right off the top make this challenging for the ideal brrrr of extracting all investment
