The first misconception is that you can declare a property headed onto the market only S8 eligible, refusing to consider traditional applicants.

While some buyers may shy away from the 7.125% interest rate, others who are familiar with the "Subject-To" strategy or are more flexible on financing terms may see it as an opportunity to acquire a property with decent equity and no need to qualify for traditional financing.

Will likely take longer to close than a traditional hard money (they have to order an appraisal, satisfy lender conditions etc..).

Often, traditional lenders offer better rates, which can significantly improve your profit margins.2.

You would only pay taxes on all passive investments in a traditional SDIRA at distribution, unless you have a mortgage, then the portion of the income derived because of the mortgage will be subject to UDFI (unrelated debt finance income) which will trigger UBIT (unrelated business income tax). 

Typically most DSCR lenders follow a traditional 5, 4, 3, 2, 1, PPP or a 3,2,1 PPP.

.- The 203(k) will allow you to bid on properties that need repairs that won't qualify for a traditional mortgage => less competition => better purchase price.You will need to find a great local contractor you can trust to supply the required bids to qualify for the 203(k).- After closing, you can do some of the work yourself to save money, but the program doesn't allow you to pay yourself.You will want to buy a Class B property, maybe Class C+, in an area that seems to be improving.

If you go with your traditional family insurance premiums will be about twice this, since they don’t specialize in this market.b.

I have used both Traditional (pre-tax) funds, Roth and HSA.

I agree that DealCheck (or the BP calculator) does not provide enough tools or functionality to analyze those types of transactions (yet).But I would argue that it does a great job at analyzing more traditional buy & hold SFRs and multi-families, as well as flips and rehab projects.
