If they move out somewhere else the problem can become (out of sight,out of mind) for the sellers.To Chris mason's point about in writing it's also that way from a lender's standpoint on a loan.

You're likely to get only a few hundred dollars per month of cash flow from your properties and putting that toward their mortgages will not really pay down the principle that fast, especially considering that you pay more interest than principle at the beginning.You're also buying turnkeys - so you will purchase them at market prices.

I certainly do agree with you @Larry T. on the ethical principles of realtors and Wholesalers...

Ok Stephen heres the deal i have to do the repairs and the payments are 1500 a month right now there are 2 apartment rented the first floor has to be done over complete to make it an apartment the two rents equal the 1500 the new apartment would bring in 1300 a month taxes are 5500 water an sewer are 1050 ins 2400 snow removal 500a year put  away 500a ayear for repairs the 1500 goes towards the principle theres no interest and the balloon payment in 5 years

I wouldn't be concerned unless you are buying sight unseen.

We primarily wholesale at the moment with our sights set on other investment strategies in the long term!

To think that low interest rates from 2000 to 2007 did not have anything to do with the 2008 crash is perhaps a little short sighted.

I was paying over $600 in interest and under $200 in principle.

Well, you can get private money, at least in principle.

Generally with a HML you pay interest only on the principle.
