A secure email can be had thru a private business server, above my level, but many title companies and banks use them for this exact reason.

I am only a server at the moment so my income is on the lower end but it will be almost doubling by March of next year which will put a boost on my savings. 

Then I have to have a process server serve them. 

Portfolio lenders and commercial lenders that do no have a seasoning requirement nor a max number of loans, although their terms are not as desirable as Fannie / Freddie.Here's my question: if the investor has not maxed out his Fannie / Freddie loan slots, is there any disadvantage to first dealing with a portfolio lender or commercial lender and conducting many BRRRRs in a short amount of time, taking that approach as far as you can, and then moving on to conventional Fannie / Freddie loans?

I'd take advantage of those remaining fannie slots as much as I can before pushing portfolio lenders, unless you get great terms.

No reason needed, just be sure to have your notice served properly, by either 1.)serving them personally and have them sign for it, 2.)post it/ mail it/cert mail it or a 3rd option use a private process server.

Will he be installing a new water heater with gold inlays and a built in internet server?

I just know there will be a mostly consistent 9 hour time slot where I may not be available on. 

You'll need to have them served with the paperwork though, which you could do through a process server local to them if you know where they live.
