I agree with John and Daniel that mostly your efforts should be focused on finding deals, but you do need to start building buyer relationships right away - you definitely need buyers, and finding one with no time to spare (after you get a contract signed) can be challenging.Google the typical REI phrases like "sell my house fast" etc. and call the top ones - tell them you have a deal IN THE WORKS (typical 3/2/2 blah blah blah) and you just want to see if they will be interested if you get it under contract.  

If they don't have that in spare cash, many people can borrow from their 401K, not withdraw, borrow.

Need to be able to store spare appliances or quickly fix  appliances.  

This income has allowed me to invest every spare dollar into real estate at a rate faster than most college dropouts.  

You can become a real estate agent anytime – I just did, in my spare time, and I have a Masters degree.

Then all of the extra supplies (ordered in bulk from Costco) go in these closets, along with spare linens, beddings and towels.Good cleaners will do whatever you instruct them to do.

If your looking to get into rentals the ones I recommend are:"How I turned 1000 into 1 (3.5, 5) million in my spare time investing in real estate" - By William Nickerson.

I went to pry it up to replace it with a spare and the whole tile came up w/o any effort, that's when I noticed it was pure black underneath and the surrounding tiles all came up with very little effort too.

I usually keep spares locked up or I end up with three half empties.( People  always seem to think half full tanks are empty for some reason) Take them to get filled, exchange stiffs you by 25%

We brought in a bunch of crushed concrete and compacted it .
