We did not assign them to Trust or anything like that, were just keeping them in the LLC and running them as an extension of our personal finances.

Duke,Glad to see you've received an extensive feedback with the detailed explanation of various funds' options as well as pros and cons from such experts as Mike Dymski and @Brian Burke. 

For example it will be nearly impossible to find anything priced at 70% of ARV, and you may end up needing to do extensive renovation because many of the properties that required minimal work to flip have already been flipped.

Now that will cost you, but in general, the cost of an agent is returned by the higher sale price due to the more extensive marketing achieved through the MLS.

I am waiting for his 2018 tax return (he got an extension), then based on what I can figure the expenses to be, will send him a letter of intent to get into see the units.

make sure to have gutters, and extensions on down spouts. 

@Michael Schmeling, as long as you sell the property so that you have lived in it for two out of the five years prior to sale ( and actually you'll get an extension because of your active duty station) you can take the primary residence exemption and the first $250K of profit will be tax free. 

I have individual clients with net worth from 1 million to over 100 million and 16 years in the business.Whoever you talk to make sure they have extensive experience and credentials to help you.

We have done extensive renovation and construction to add value.

Usually, there's an x-day extension already in the contract, standard is 10-day in ours, if needed for loan or title issues, which this should cover.
