Despite what many people may lead you to believe, building up a real estate portfolio takes time and discipline--it doesn't just happen overnight and that goes for any market (no matter how inexpensive or expensive it might be). 

Is your desire to finance 100% because it genuinely works and makes sense  or because you don't have patience and discipline to get a down payment.If you finance 100% and are in a position where you need to sell it sooner than later but have little equity, you will probably have to come up with cash to sell it off after all costs involved with selling.

Hang in there and maintain discipline.

What are the thoughts out there taking on both disciplines? 

Discipline yourself on the rehab.

There’s a line between investing and speculating that maybe gets more blurry and easier to accidentally cross when discipline is replaced with fervor.

Will you be disciplined to get things done each day if you don't have a boss asking for your work?  

I would rather have an empty unit for 6 months than to let the wrong person in you have to be very disciplined in selecting proper tenants.

(Side Note: if you really want to jump your credit score in a few months (because it takes time for the reporting to update), and if your disciplined with your spending try this;1st) I went and did the math to see what my positive cash flow each month off my active income (let’s say you’ve got $500 left over after you go through your monthly spending avg. which is all you kick out vs what you bring in)2nd) Go get a credit card with 0% interest for 12mths with NO higher than 5% transfer fee.( their are some with low as a 0% transfer and I had got that one on my 2nd round cause my credit wouldn’t let me at first)3rd) do a transfer balance after 24- 48hrs of opening the card (Nope you don’t need wait to actually get the card just call in and tell them over the phone to send a Blanche transfer check to your bank account in the amount of your car Balance; because you’ve only got a 30day window of transfer with 0% interest for the 12mths)4th) PAY YOUR CAR OFF IN FULL, and take your old car note (let’s says it $450mth) plus your $500 positive cash each month and add all $950 each month to pay against the balance on the card5th) in 45days start checking your CreditKarma app (its free) and don’t worry about the 5% if it’s larger than your car loan % because once you’ve paid your car off your score will go up and in a couple months of $950 your car will be paid OFF not in 2more years or so...Thus saving you probably more than $2,000 in interest on the car loan (so you get to keep $$) and time in payments.Your saving money on interest (keeping it in your pocket thus making your pocket bigger!

I know that I have the discipline to apply this method "safely" and am kind of excited to employ it.
