Go luxury sooner, so your commissions are higher than the sub-$300k stuff that a lot of Realtors are more comfortable doing and if you land a big listing, you could always partner with another more successful luxury Realtor who would be happy to co-list and cover the cost of the luxury marketing if you're bringing the listing to the table...Hope this helps! 

I have people that run it down to lightbulbs, each light switch and outlet cover is counted and figured in to their analysis. 17 pages of SKU numbers from Home Depot or Lowes, who they are having lay carpet and the cost they are paying.

Not much I can’t fix, but if I do I work in construction and have all professions covered with cheap weekend labor. 

Second, there are 50 states in the United States and EVERY state has different laws so there is no way for one "simple" system to cover all 50 states, all types of sales, all types of financing.  

And it's unlikely you're going private lenders willing to do 7-figure loans in the 6% range, unless you're willing to give a personal guarantee and have collateral to cover the full loan amount.Personally, I've done loans in this range, but only under circumstances where my risk of loss was literally about 0%. 

,etc.I would want to see pictures they took of the renovation and replacing everything.

Helps knowing the rate/term you should have.Take lots of pictures before and after the Rehab.  

You usually have liability insurance to cover yourself.

I would like to not make any more contributions to the condo when I leave, which means renters would cover mortgage + HOA fee.

So if I wanted to do a flip in my 401k I could get a non-recourse loan at, say, 12% interest to cover the cost of the flip and I would pay no UBIT.
