I don't say that to be self-serving, being a lender.

If you just handled it on your own/contractor self-mitigation, you would need to have some proof it was handled.

We (my wife and I) have been at it for a few years - self managing mid and short term rentals.

I hope you are asking two separate unrelated questions, because there's no point in doing cost segregation for properties held inside your self-directed solo 401k, save for some very rare exceptions.Some of the Bigger Pockets experts who operate reputable costs segregation companies are @Bernard Reisz, @Yonah Weiss and @Julio GonzalezSome of the Bigger Pockets experts who offer Solo 401k administrator services are @Dmitriy Fomichenko, again @Bernard Reisz and @Brian EastmanReach out to them and see if they can help.

Remember, the notion of amassing wealth without investing is a dangerous myth perpetuated by self-proclaimed experts.

I self manage 29 SFR and do all my taxes on turbo tax.

So if you are going to be a host that outperforms your competitors and want to get fabulous reviews, there isn’t complete down time if you are self managing at the highest level.

I have had thoughts and considerations of doing such a thing for some time but wondered would it be something worth doing, as in people would use it, find value in it, enough to offset the time and investment of self into creating and maintaining it. 

Love the hustle and that you self-manage.   

I have a few reasons for this. 1) We are both self-employed and our income is inconsistent. 2) We don't want to impact our DTI, because we are planning on buying a house hack within the next year or so.We would be open to going up to 6 units for our first property as long as it's within budget.Now that you have some context, is it possible for a rookie to use a DSCR loan on a duplex or triplex?
