Put in the contract, I will pay off whatever they still owe to the bank at the time I pay off their loan or exercise my L/O so they don’t have to worry about the potential (and probable if a newer loan) to owe more than I owe them.

A word of caution to readers: if you are considering something like that be sure to do further research and read opinions and studies or independent parties (many studies and marketing out there is by companies who sell those products and are biased and you have to exercise discernment to sort out that junk). 

When you advertise, cut down the number of bedrooms (you now have offices, study, and exercise rooms).

And the info and exercises you'll go through tend to be deeply changing for most who attend.

I am just exercising my rights underthe laws that they set up.

That might be a hands and knees exercise, but will save you unnecessary labor and expenses.

I'm not so sure that the fact the lender is waiving its right to exercise its option to call the note immediately would prevent it from exercising that right at a later date.

This Execute, Rinse, Repeat exercise adds you 1 solid property a year.If you have additional savings based on having your house partially rented and cash flow off the properties you're accumulating, you can look to use that money for down payments on other more turn key properties to more quickly grow your portfolio.

JP even if the lender is in a state where they do have a right to exercise or enforce a deficiency judgement, sometimes you can do a short sale and use that as leverage for them to release any responsbility on the seller once the home has re-sold, instead of them getting absolutely nothing if the house just goes back REO.

I'm considering offering a lease/option on a low-end SFR in Las Vegas ... have been told by various contacts the percentage of tenants that actually exercise their option to buy the property is somewhere between 5 and 25%.
