Is there a percentage or rule of thumb?

.- I have to work under a broker for 2 years before I can apply for my brokers license in state of FL- I have to split my commission profit with broker and all funds/payments must be made out directly to the broker- the percentage commission I negotiate with property owners is my decisionDetermine best path to form Vacation Rental Property Management company being aware of my new status a sales associate- can I start my own business entity to establish and brand my VR management company now, or would/should I just wait the 2 years, get brokers license and then do so.

My father in law is a contractor and said he would be willing to do the rehab for a percentage of the equity/cash flow.

Depending on how many mortgaged properties you have it's now a percentage.

More than likely the cap rates would be different so unless the income is such a small percentage of total income it is better to value separately.

If your strategy is to buy deferred maintenance properties and rehab and hold for retirement, then you might want to hold title in an LLC, and sell a certain percentage of your LLC to a self-directed IRA.  

My understanding is that you essentially renew your mortgage for hopefully a lower rate/ payment, and pull out a percentage against the value of the home (example: 70% LTV)  but does that start the timeline of the mortgage over again?

This assures the highest percentage of hassle free land lording, in my opinion.

I understand what it is and how to calculate it, but it just seems like the number could very easily be distorted depending on what percentages you're taking out for vacancy, repairs and maintenance, etc.

After 10 units, then the numbers work for me and vacancy percentages aren't as much of a concern.
