How much is fix up with an extra 20% fudge factor for problems that will occur? 

I"m earning less than 50 basis points on my savings accounts and most banks are paying less than 2% on longer-term CDs from what I've seen.

If the Seller wants to try the rent-to-buy scenario, he could also put that idea to his existing tenants as incentive for them to pay him extra per month?

Rather than insist that everyone has to earn less for your sake, you adjust your budget accordingly. 

I'm looking to start wholesaling to gain some experience and extra cash at the same time.

How much income to I need to earn in order to qualify for this kind of money?

I'm looking at a house that could be flipped and held.I'd also like to have the extra acreage it has and block it off for RV's to come and hook up, I'm however confused on if I should purchase this property as an LLC(which I haven't created yet) or if I should buy it as my personal estate and just rent out sections of land.

Instead of looking at putting down extra money to reach your LTV necessary to eliminate it, potentially look into requesting a new appraisal if you think the value has gone up from your purchase.  

If you want to roll three properties into one large purchase you may want to consider a reverse exchange to make sure you buy exactly the right property and get some extra time to sell the old properties.

I earned my salesperson license to help my investing.
