Also, you extra cost is on the delta of the bridge loan vs what a conventional loan rate is.

@Dav PohoteThe answer is it depends,Currently you may be much better off at 15 years due to where interest rates are but when they were 3-4% you could have invested the delta between A 15 and 30 year payment and achieved a return better than the interest you were savingIt’s also a personal preference where people like to have less debt and sleep better at night - I am 100% with that being the reason to do 15 %For example for us our primary is 30 year at 3% and we have a rental that we 15 year at 2.5% and reason we did 15 year on it was it matures the year my son will go to college and we did not “need” the cash flow during this time so we were like let’s have it paid off and then it’s cash flow can be used for his schooling or sell it to pay for school.Lots of things to consider and each situation should fit your needs

Investing that delta may have you break even after taxes versus mortgage.

I utilized the pandemic to make HCOL wages in a LCOL area and am trying to take the delta and put it into something which generates cash flow because my retirement is essentially fully funded. 

Then you have owners who have debt and want to wrap the loan and sell and make the delta I like this the best as they will stay in the game  they have control of the underlying debt and they have a document ( all inclusive Deed of Trust) that they can foreclose out the owner finance buyer.

But, I will lower my monthly obligation to around $3000-3500 ($2500 new mortgage plus $500 delta on previous home mortgage). 

But with very little equity.. and of course they got into these deals with very little down payment to no down payment.. then they turned around and leased with option to buy and were making about a 200.00 delta.. per property..

A lot of Delta Air Lines employees opt to live south of the city for easy access & less traffic to reach the airport.

So if your strategy is to use rentals to cover the delta between your current mortgage and the mortgage of your dream home, you’re probably 10-15 years off from being able to do that.

Better yet and probably and easier sell.. is to have the seller wrap their own first and let them make some delta..
