Again though, I like that they have so many resources, checks, and balances at their disposal to get us through the deal smoothly.  

One challenge I found is balancing the work/life balance in the house.

If this isn't a separate dwelling unit you can't take losses from the rooms / space you are renting and use them to offset non-passive income (Section 280A of the tax code)Rental expenses are limited to the amount of your rental income and the balance of rental expenses is carried forward.

For example, your credit card could have a line of credit up to $25,000 but you don't pay anything as long as your balance is $0.

I am planning to go with them for real estate, once I complete re-balancing portfolio - they are located in Houston is a big plus!

However, those typically have a loan min balance of 400k or more.

You asked about a property you have listed for sale and property taxes that are coming due and the consequences of not paying them until the property sells.Generally, the local taxing authority will impose an interest penalty on any unpaid balance after the due date with a long grace period before you would have to worry about unpaid property taxes affecting your ownership of the property or your ability to sell.In all likelihood, the property taxes will become a part of the closing and will be deducted from your proceeds at the time of sale.By the way, property taxes are always in first lien position ahead of any other debts like mortgages.

I am a real estate agent + I'm in the middle of a gut rehab and it's hard to balance all of this with family ( kids + partner)

I think both need a great deal of people skills being able to deal with multiple different people with multiple different desires in the transaction and being able to balance all of that is hard work in of itself.
