A cost segregation study basically separates your property into components that can be depreciated faster than the standard 27.5-year schedule.

If most interested in house hacking I would learn how to evaluate those deals good and learn basic property management.

Hey Jonah,i use the most basic quickbooks subscription for 9doors.

With tax season here, I’ve been talking to a lot of real estate investors who work from home — and I keep seeing the same thing come up.They have a home office…but they don’t realize how powerful it can be when it’s set up correctly.Most people focus on the home office deduction itself.That’s helpful — but here’s the part many investors miss:A properly established home office can unlock mileage deductions.When your home office qualifies as your principal place of business, trips from your home to properties, job sites, meetings, supply stores, or lenders can be treated as business mileage, not commuting.That’s a big deal.Without a qualifying home office, those same trips often get treated as nondeductible commuting miles.With one, they may become legitimate business deductions — which adds up quickly over a year.Of course, the home office still has to meet the basic rules:Used regularly and exclusively for your real estate activityClearly tied to management, analysis, bookkeeping, or operationsDocumented properlyWhen it’s done right, a home office doesn’t just reduce expenses — it changes how travel is treated altogether.If you’re running rentals, STRs, or active real estate work from home, tax season is a good time to double-check whether your setup actually qualifies — and whether you’re taking full advantage of it.For those investing from home — do you currently track mileage tied to your real estate activity?

I basically started off doing this on my own.

Most cost seg firms will give you a free estimate if you share basic property details - no commitment needed.For residential STR properties in the $500k-$1M range, check out room42.io - they're built for this exact use case and the cost is low enough that you can run studies on multiple properties to dial in your estimates without breaking the bank.

Quote from @Frank Pyle: Yeah for small multifamily, ARV is basically stabilized NOI divided by a cap rate, but the cap rate is the whole game and it rarely comes from perfect 8 unit comps in the same few blocks.Most appraisers I see will triangulate it using any recent sales they can support, even if that means 4 to 6 units, 10 to 20 units, nearby neighborhoods, and older sales adjusted for market movement.

They told me that they would not fix anything unless I "removed the post" and basically forced me to post a retraction on here. 

I want to ask them basic questions like what experience they have managing rentals personally, how many doors their company manages, how long they have been in business, and what they feel their company’s strengths are.

Focus on basic houses that only need visible cosmetic work and are easy to resell.
