I would not factor in much, if any % for yearly increase.

Is it possible or a good ideal to wholesale properties that are currently listed with a real estate agent?

As Ned mentioned, even though some of these expenses only occur once in a few years, they can be quite high and must be factored in if you are to stay in business long term.If your expenses are 50%, then you will only have $262.50 left for the mortgage payment and any cash flow.

There are many factors beyond salaries and you need to consider those all together in understanding prices not just now but in the future.

I mean...with 2-4 properties I think it's manageble....but how do I deal with this risk ?

Add in the factors mentioned in my previous post, and you have a reduced value in terms of what a lender is willing to use as a basis for the amount they will finance.Should the appraiser always use the most recent comps?

There is supply/demand factors in play.

Try to determine all the things that could go wrong and factor it into my number knowing expenses could be worse than 50 percent.

Buying foreclosed properties from a bank is fine way to buy and may be ideal for your area if there is a high foreclosure rate.

Ideally, we are looking to bid between 2001 and 2003 prices of those houses.
