The amount you save plus the experience you gain is priceless.3. 

On a recent one, we needed $7k added back, I felt we had $9500 in clear "one time" stuff, the underwriter came up with $4200 and we had to fight/escalate to get a smidgen over $7k to make the deal work (this was a refi of some other property to save a few bucks a month, not a purchase mortgage, so I felt OK about taking this risk). 

I have been preapproved for a loan, and have some money saved for a down payment but I would be dipping into saving and rainy day funds that I would rather protect. 

But I quickly realized that saving up to buy more rentals all by myself was a much slower process than I would have liked. 

@Michael GessnerYou may want to look into structuring the GS and Fix and Flip businesses as S-corps.There is potential self-employment tax savings going this route. 

However we are the number 1 seller in the greater Cleveland area so it has proven to be the most effective method on the planet to moving investment property in the Cleveland area.

As of now, I have 15K saved up.

Buy a small file cabinet and get your last free years tax stuff, LESs, monthly bank statements, and soon HUD-1s and stuff all it in there.4) Save for your first one, but refi for your next couple!

So should I cough up that cash for the piece of having a solid lease from an attorney or can I save that hard earned money and just use the best one I find online?

Most of those are pretty standard .. you may save a few hundred elsewhere but you will gain the headache of going through the process again.
