@Ani Nambula I'm in a similar position. I'm in the Arlington, VA area looking to pick up an apartment with 20-30 units. I've looked at as much as I can on the BP Marketplace, LoopNet, Cityfeet, etc, and can't find anything close that's within the specs I'm looking for. I think I'm at the point where I need to accept that I need to look at another market if I want to get a property that meets my specs. This is difficult when you work full time. I think you see a lot of the "masters" will up and move to their target market, or spend considerable time building a team in that market. Right now I'm trying to figure out what market that is for me then
1) Visit that market, understand the neighborhoods, visit properties. This might take 2-3 months with several visits.
2) Develop relationships with brokers in that market. From what I gather, checking the MLS like you might do with a SFR is not very effective when looking for 5+ units. So take some action and call some brokers. But don't waste their time if you don't have the potential to get the finding.
Best of luck and I hope we get to hear about your journey soon.
