It's not necessary to have them all sign the same copy of the signature page of the sales agreement, you could send a copy of the page to each and have them sign it - along with a witness - and send/facsimile it back to you.Naturally, you should seek advice from your attorney in this matter on which avenue would be the easiest, most cost efficient and expedient. 

If you happen to live in an area (or are comfortable travelling to an area) where it is efficient (I'm arbitrarily saying efficient is that for every 100 properties you view, you make 10 offers, of which, 1 is accepted), the the rest of this point is moot since that is fairly easy to scale up (as in a small team can probably view 1000 properties annually while the wealth is compounding).

I think it's best to spend my time and energy finding new tenants instead of chasing old deadbeat ones.

Heat pumps also act as central air in the summer months.The Mitsubishi H2i ductless mini split heat pumps heat down to -15 and no backup source of heat is needed and is more efficient then even a high efficiency gas furnace, which is ridiculous.... but they are very expensive.IMHO,Gas heat is the cheapest when balancing up front installation cost and long term utility costWe are talking a $22.50 difference between gas or electric per 1,000,000 BTUs burned.

From an actionable point of view, if you plan on investing as a sole-proprietor, it's better to put all of your time and energy into finding and getting into your first deal, rather than setting up an LLC.

After several years of representing buyers and sellers in California, I decided to focus all of my energy and experience toward investing.  

Is this the best option for me as well.I am just trying to make sure I am buying and selling property the most efficient way.  

Glad you had the guts to stick it out and the energy to find the right people to help you through it.  

The newer refrigerants are less efficient, so the higher SEER requirement leads to higher costs.Also, there's no such thing as "freon".

I would put time and energy into learning about notes.
