So if you're a sole proprietor applying for an EIDL, that would mean that its a general UCC-1 w/o specific collateral, and not attached to your real estate assets (rental properties).I am not an attorney.UCC FilingsUCC Filings 2EIDL UCC-1Another link

Schedule C if you a sole proprietor) & you do not have any full-time w-2 employees (i.e. working 1000 hours or more per year or 500 hours per year in 3 consecutive years) working for your self-employed business or otherwise.Please see the following regarding Considerations re Investing in Real Estate & Considerations re Choosing a Solo 401k provider:General Considerations Re Investing Retirement Funds in Real Estate:1.

@Dustin PetersIf you are self-employed with no full-time employees (even though you have a separate w-2 job), you would be eligible to establish a self-directed Solo 401k.You could then make contributions to the Solo 401k from your self-employment income (i.e. w-2 income when your business is taxed as an S-corporation, 1099-misc income if you are a sole proprietor).If your plan allows for it, you can make pre-tax, Roth (or even additional voluntary after-tax) contributions.Contributions can be made as both employee and employer contributions (since you wear both hats):The employee contribution limit is 100% of your w-2 wages up to $19,500 (or an additional $6,500 if you are 50 or older) provided that you are not making employee contributions to another plan (e.g. if you have a day job with a 401k plan).

But if you use an LLC that is disregarded (it doesn't file its own tax return and is taxed as a sole proprietor) then you personally and the LLC are considered the same entity for 1031 purposes under law now. 

However, when you start talking LLCs that can change things - or not.For 1031 purposes, an LLC that only has one member (you and your wife and the joint return) and chooses to be taxed as a sole proprietor is considered a disregarded entity. 

Is an LLC Sole Proprietor or LLC S-Corp better to qualify for a mortgage?

Did you use a partnership or a sole proprietor with the other spouse as the employee? 

The state of MA has differences between being a sole proprietor and being a single member LLC.

They're just going to drag you down even more.But you may not have to choose between a refi and personal financing vs 1031 and commercial.If the LLC that you own the property in now is a disregarded entity (meaning it has only one member, has chosen to be taxed as a sole proprietor so it does not file it's own tax return) then it would considered a "disregarded entity". 

The founder(my partner), who is the sole-proprietor's son had passed away suddenly which left almost everything on Diane and I.
