It really depends on hundreds of factors.

These are the key factors you need to be sucessful in the model you propose.In addition, simultaneous closings (where you use your end buyer's funds to close your purchase transaction - using buyer C to close the A-B transaction) are very difficult at best these days due to the many law changes and the title companies not insuring the transactions or willing to perform such transaction.

I dont have a strong understanding on "delinquent condo fees" and how that plays a factor in investing in a condo.

I deal with Regions bank and they have a charge for bank checks but give me all I want at NC due to my relationship with my banker.

I guess my situation could be worse, but I have a great multifamily under contract which very conservatively needs about $20k worth of work to be 'nicely' fixed up- new stucco, paint, carpet, updating bathrooms and kitchens, etc.The problem is I already have an FHA loan, and won't qualify for the ideal FHA 203k program.

The other factor is that banks want to see the borrower have some "skin in the game"...when you are 100% leveraged on a property (even one where the value is significantly higher than what you purchased it for), it's pretty easy for you to just walk away on a whim.

All these things factored in would seem to make it difficult to compare yearly income to purchase price.

So many factors to consider.

I'm just using this for planning factors.
