The risk here, I imagine, is that if you do have a vacancy it could be a big ouch once a HELOC is used to extract cash for the next investment. 

There are several specialty providers active here on BP that offer the Solo 401(k) as it should be implemented, where you as trustee have full control, and where you will have access to ongoing meaningful support as you utilize the plan.About a dozen times a year, we have the opportunity to dig an investor out of a hole because they signed up for a set of documents and only learned later they were missing the real important pieces of the Solo 401(k).

This condenser issue also has not been addressed by the sellers in a meaningful way to properly fix. 

In PA, revocable trusts generally offer no meaningful asset protection.

Some key numbers extracted from the screenshot below: - Purchase Price: $95k- Rental Income per unit (monthly): $670 (based on myrentrates analysis for 1BR 1BAs)- Units: 4- Repair Costs: $15k (total guess, but even with a $100k rehab/repair cost the ROI would be 12.9%). - Cash Flow per door: $340.29- Cash Flow, all units: $1361.16- CoC ROI 39.26%

We end up with an investment cost to value of 8.4% (started with just over 21% investment cost to value).It would be nice if we could get 100% of our full investment out but so far we are not there unless we have had some market appreciation (most of our RE we have all money extracted but it was helped by the market appreciation). 

Did you find it extremely dull and hard to extract a lot of concrete knowledge from it?

These are hyper local so it’s tough to do in this space, and, importantly, it is likely a small portion of your overall housing payment, relative to the cost of rent or mortgage so even if they appreciate faster than rents appreciate the basis is lower and they won’t catch up to make a meaningful difference in our decision.

A poor credit score is meaningful. 

The meaningful appraisal worth paying for is the one that reflects the added value of a significant rehab, and once you have it--the first appraisal is rendered a meaningless waste of money.
