I am in the Baltimore market which is probably harder than Florida however I'm sure there are still high cash flow low entry high risk properties though a lesser percentage. 

What percentage of a deal is fair for me to ask for when I bring a good cash flowing deal to the table?

Those are great questions to ask in terms of overall demand however they are subjective and based on opinion not fact or hard data.Follow up questions would be how many houses are on the market and how long have they been on the market, how many houses are under contract how long have they been on the market, how many houses have sold in the last six months and 12 months and how long were they on the market and what percentage of asking price did they close at? 

The origination fee might differ from lender to lender, but my guess is that it will be a percentage, and you will have a new loan balance. 

On the ARV and LTV the difference is most lenders will go up to a certain percentage of ARV (e.g. the ARV is 200K so they can lend up to 150K between purchase and rehab combined).

Have you ever spent a "percentage" in your life? 

I think if you focus on the debt that's all that will change, if you focus on growing your rentals, your income and cash flow will grow making your loans a smaller percentage of your focus! 

Dear BP family,As an investor I'm interested in paying as low as possible for a deposit.But a contractor obviously wants as much as possible justifying that he needs to buy materials and pay his workers.What is the best strategy to negotiate down the deposit and how much (percentage wise) is the standard for a deposit?

You could set up the LLC that they receive an agreed percentage amount based upon risk, their goals, and exposure.

So, then the crime statistic percentages are based on the full-time residents, not counting visitors, and it throws everything off.
