Being a "Real Estate Professional" has great tax benefits if you qualify.

@Phillip TomassoYou want a line of credit .the interest rate will be around 10% though but you get one great benefit .

It might mean a little bit longer vacancy timeframe but being able to communicate the benefits of someone in the long run that will cost less over their lease is worth it.

So, if I were to sell it by 2020 (within 3 years of turning it into rental), I pocket the entire capital gains on the property (roughly $65k) but I will instantly lose my $750/monthly cash flow from rent as well as all other tax deductions and depreciation I could benefit from each year. 

I personally don't use the app and just open BP using my web browser on my phone or Tablet...from what I've seen BP's website is very mobile responsive...Besides having an icon on your home screen & receiving notifications what benefit does the BP app have that can't be accessed from the web version?

Any insight would be great since this feels kind of like a win, but not sure how it benefits the buyer that much.  

I've felt I'd need to do that anyway to be serious about RE investing, and this just adds one more benefit if I sell.

Under the new tax law, is there a benefit to changing the tax status of my LLC?

Keeping that in mind, I would choose the 4 unit because the benefits of that one extra unit do not outweigh the benefits of the better financing options. 

The two common choices for doing so are the self-directed IRA and the Solo 401k.The Solo 401k requires self-employment activity, but will allow you to take participant loans while the IRA does not.A few other Solo 401k benefits:Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)With either structure, it's generally recommended that you do not commingle retirement and non-retirement assets.
