So far, we've pieced along different elements of this (different tax person each year, no LLC to one to now 2 this year, haven't yet used a bookkeeper...)trying to streamline systems and have a solid foundation for our fairly new and growing real estate portfolio. 

For example, they can finance up to 70% of the ARV meaning, if you have a perfect 70% deal (purchase price and rehab are withing 70%) they will cover those cost for you.you will still incur closing cost, taxes, and insurance cost though for example.True 100% financing (ZERO out of pocket) typically requires solid relationships with private lenders or a combination of hard money lender and private lenders.

But what are the tax implications of such a situation?

I have a good credit score, but I'm concerned that given I'm going to have very low provable income for the next 2-3 years and not be able to secure a loan especially with a low down payment.

There is definitely potential to get it lower but it seems like it is going to have to be way lower after considering the expenses that are going to come with it.The entire property has potential to bring in $3,000 worth of rental income if my rent comps are correct.

If you don't plan to create a business entity, then the only purpose I can think of for a separate account would be to help you manage and track your income and expenses.

can do no income no doc at 30% down on the purchase providing 100% of the construction 

@Alanna ThomasIf you financed your property through a lender that escrows for your taxes and insurance - that stays in place regardless of what you do with the property (ie rent it out, etc).  

Additional streams of income:1) Have mortgage broker present at open house (and charge them "$5000"%) to pre-approve those who want it (but don't make that a requirement to bid).2) Sell the bidder list to other investorsI have not seen any such ads in my area and I'm wondering if it's because this system is not effective or is it because nobody is utilizing it?

I'd then repeat this process every 12-18 months until I had a reason to stop.Concurrently I'd be trying to increase my W-2, or 1099, income as much as possible, as soon as possible.
