Going up in the morning to do all the homework on it and aim to get a signed contract with the buyer no later than Saturday.

Supplemental thoughts appreciated and thanks again.  :-)

That's what I have been aiming to do and I'm on track for that next by next year.

what I would suggest is to come up with a budget.. say $500 to $1000 per month have an expert run the ads(someone with a track record) and then see how many leads you can get the first month and focus on incrementally improving it... if you get 10 leads the first month, your focus should be to improve it the second month .. maybe aim for 15 to 20 leads... with the same spend... be sure you know your ROI - what is your return and keep improving that...one key thing to remember.. say you have a successful adwords campaign and you decide to target a different location it doesn't mean you'll get the same result...

Do you guys know where i should aim to get the maximum profit ( after expenses & credit) ?!

A duplex arrangement is what I believe I should aim for at this point.

Looks like it's the same down here, there isn't much I can find except supplemental filings. 

On some of the supplemental  forms that could be required , TDHCA will have you complete, notarization will be required.

How much should I aim to have saved for a down payment/allocate for such an investment?

If you can negotiate a purchase that is below the value of the property, plus add more value, you can get a pretty good deal.The top things that I look at are cap rate (I aim for 10%), cash flow, and value-add opportunities.
