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. 

But I’ve never personally invested in real estate using business credit more traditional for my first property, so I’m always curious when clients say they want to use this funding for a real estate deal.Here’s where I get stuck:Real estate deals can be risky, especially if the project takes longer than 12 months to close or unexpected costs pop up.With prices climbing, it feels like the margin for error is smaller than ever.Would you recommend someone use business credit to invest in real estate?

Duluth has traditionally had a strong college rental market and thankfully any small decline in enrollment rates haven't been as severe as other traditional college cities, eg.

@Neil Smith,Yes, Traditional IRA can be rolled into Solo 401K.

When you do a traditional 1031 exchange you have 45 day identification period, to provide a list of potential replacement properties and 180 days to close on a replacement.

As a side note typically I do not use my deferred tax dollars to invest in traditional real estate as the benefits (depreciation etc) are all lost when using a self directed IRA - My guess is build to rent will provide little to no cash flow to build the account - it will all be locked in the property. 

Too many varying opinions with sound logic on both sides in this forum regarding traditional velocity banking.First position HELOC ... 

Two of my units will be vacated in the next 2 months so this is a good time to consider this over my traditional 12 month leases again. 

Is there a reason why you are set on a traditional duplex? 

Honestly have never touched the traditional mortgage side of the bank.
