You sure can find opportunities sitting on the MLS. It's not everyday nor is it easy, but most things worthwhile are neither.
Most of my BRRRR deals have been through the MLS but takes some serious negotiating and knowledge of the area.
At minimum, I would want someone I trusted walking the property, and would not feel comfortable doing a rehab estimate from pictures online.
I always walk the property once with my agent, and once with my main contractor before I make an offer. All of my offers are accompanied by a market analysis and why I am offering what I am, what I plan on doing to the property (at least what I’m planning on spending for the rehab) to justify my offer. So far no one has been offended because I give reasons behind my numbers.
Remember, the answer is always no until you ask.
I just went under contract on an MLS deal I'm planning to BRRR and would be more than happy to discuss my numbers, how I got there, and my planned ROI. If you ever need a boots on the ground investor in CT let me know, always happy to analyze a deal and provide feedback.
All the best,
Bryan
