Something that just came to mind would be for my wife to simultaneously get self-employment started while working full time, would she be allowed to then start a solo 401k and do a rollover/transfer of her existing 401k?

Definitely title costs if the lender requires any endorsements, and in states that don't provide for a simultaneous issue discount.

So the excess 200k is boot and taxable- A very common outcome in simultaneous direct exchanges.You can still accomplish the sale as planned and defer all tax. 

If you are running multiple projects simultaneously you or whomever is paying for things (writing checks, swiping your credit card etc) need to have a procedure for making sure each expense or cost goes to the right property.

I am used to dealing with several move ins, move outs, emergency repairs while still dealing with the operations of homes and buildings simultaneously.

This is pretty inexpensive as we only need a few Netflix accounts to cover all of the units (Netflix allows up to 4 simultaneous streams).I have some strong opinions on user friendliness though!

I think a good strategy to execute on is to start with building out your SEO, while you are doing that simultaneously run paid traffic. as you will see SEO takes time and paid traffic gives you results in a very short amount of time.

Intelligence is the ability to simultaneously hold two opposing views and yet remain sane and productive.Everyone here who is bashing the OP suffer from cognitive dissonance.It probably hurts because it reveals what they’ve been subconsciously ignoring.For example,Like tons of other BP users,I’ve read so much material here over the years touting the superiority of large apartment deals over smaller ones.It’s a key reason Grant Cardone’s podcast remains the most popular in BP’s entire podcasting history.However,Having just made the switch myself and had the first hand experience,the reality is way different.No one remembers to tell you how much bigger the surprise expenses are with the bigger deals.One roof,one boiler needing replacing could simultaneously wipe out your reserves PLUS entire year’s cash flow EVEN after accounting for CapEx and repairs in your BP calculator for your original LOI.At least with my duplexes,I can replace a roof for $7000.And all my duplexes don’t ever need new roofs all at once.My apartment’s roof cost $30k just last month.Again,No need shooting the messenger.Appreciate the little voice that keeps you humble.

You'd get a hybrid of benefits of primary residence for 1/4 of the property and the other 3/4ths of the property you can depreciate, and write off expenses as if you're running a business so it provides a tax shelter for your business related activities while simultaneously still providing you that tax free primary residence exemption (IRC 121) on 1/4th of the sqft of your home so 1/4th of 250k single or 500k married means you can get 1/4th of that tax free of the gain potentially.

When you reach the desired "width" of flip properties, you use to the profits from all these simultaneous flips to buy holds (among other uses for it).
