Does the platform actually vet the sponsor or just post what the sponsor sends them

The short answer is: it varies a lot, and you cannot assume the platform's process substitutes for your own.

The larger platforms do run real processes. RealtyMogul, for example, has published that they review a small fraction of the deals submitted to them, which implies a filter exists. CrowdStreet historically reviewed sponsor track records, financials, and market assumptions before listing. But "reviewed" is doing a lot of work in those sentences. What the review covers, how deep it goes, and who runs it differs by platform and is rarely disclosed in enough detail to evaluate from the outside. A platform's incentive is partly to list deals, which is worth keeping in mind.

The honest gap you found, no addresses, no exit numbers, is a real gap. A completed project with no verifiable exit data is not a track record you can use. The two you confirmed through county records tell you the sponsor finished something. They do not tell you whether investors made money, whether the timeline held, or what the actual returns were.

The thing worth knowing here: "preferred return" (the 14% figure) means investors get paid that rate before the sponsor takes profit. It is a target and a priority position, not a guarantee. Whether cash flow from a 22-unit gut rehab in 18 months can actually support it depends on the construction budget, the pro forma rents, and the exit assumption, all of which you should be able to request directly from the sponsor as a prospective investor.

You can ask the sponsor for addresses and actual exit figures on their prior deals. If they decline, that tells you something.

What would help me give you more specific direction: are you looking at this as a debt position or an equity position, and do you know which it is?

The process varies, but not randomly. Platforms operating under Regulation A or Regulation CF have SEC filing obligations that create at least a paper trail you can pull yourself on EDGAR. Regulation D offerings, which most of the bigger equity deals are, carry far lighter disclosure requirements, so the platform's internal process is doing most of the work and you have no external check on whether that process is serious.

The honest structural problem is that platforms earn fees when deals fund, which is not an incentive to kill a deal over incomplete sponsor history. Some of the larger ones do run background checks, pull entity records, call references, and require audited financials on prior projects. Others are closer to what you described: a formatted upload. The difference is usually visible in what they publish, specifically whether they show actual exit IRRs with dates, the entity name the prior deals closed under, and whether the background check methodology is named anywhere in their offering documents.

What you found by tracking county records yourself is the right instinct and the right method. The question I would push on: did those two closed projects involve the same entity or principal name listed on this offering, and do the county records show a lender release that confirms the project actually performed rather than just transferred?

The three completed projects with no addresses and no exit numbers would have stopped me cold, and the fact that you had to find the city names from a podcast tells you exactly how much the platform contributed.

RealtyMogul has talked publicly about background checks, reference calls, and financial statement review, but I have never seen a platform publish what they actually rejected and why, which would be the only number that tells you anything real about the process.

What was the sponsor's entity name on the county records you pulled, and does it match anything on the platform page?
