I've been studying the BRRRR real estate investing method and the theory makes perfect sense. My hangup is on the first 'R'—the renovation. Every case study seems to find a property needing only cosmetic updates that come in under budget. In the real world, how do you accurately assess rehab costs on a property you don't own yet, especially with hidden issues?
You're not alone in this The rehab plan starts with a careful scope Before you own build a scope of work with line items for cosmetic updates major systems (roof foundation HVAC plumbing electrical) permits and a contingency 10 20% of hard costs Then get 2 3 contractor rough quotes on the big items and use those numbers to sanity check an overall rehab budget against your target ARV Rehab budgets always shift so build in flex
Hidden issues are the real trap Photos and descriptions miss things like hidden water damage structural problems or outdated wiring If possible schedule a pre offer walk through with a general contractor and ask for a rough scope of work with a high level cost Bring in a home inspector during due diligence even if you don t own yet if the seller will allow it an inspection contingency can help
Use a simple check list to evaluate roof condition foundation cracks drainage HVAC age plumbing material electrical panel moisture signs If red flags appear budget for an engineer s assessment and a more thorough cost estimate for rehab
Estimate approach start with ARV from recent comps subtract estimated after repair costs add a contingency and the holding costs This helps you see if the rehab actually pencils out If the numbers don t pencil it s a red flag
Negotiation tip when possible ask for seller credits for known repairs or structure the deal so the rehab is funded later A clear scope of work with quotes helps keep the rehab on track and reduces surprises
Documentation matters keep a rehab plan doc listing scope quotes decisions and changes this helps you stay honest about budget and timeline and it gives you something to compare against as you move into ownership
