A blanket loan will not lower your dti because the loan amount would be the combination of all 4 properties, which is the same as them being separate.

stay in the game".You have to understand what a loss is...and combining #1 and #2 above should help. 

I like 15% combined.

Or a combination of the HELOC and cash out refi?

I am looking to get rid of the hassle of maintaining the laundry and dryer equipment and thinking of simply having a company take over.

Full sized washer and dryer on main floor and a pantry.

This 3 Bedroom / 2.5 bath home comes with a series of upgrades including: distressed wood flooring, custom lighting, granite countertops throughout the house, custom paint, new dual pane windows and sliding door, custom tile work, built-in audio system in master bedroom and living room, stainless steel appliances, built-in wine fridge, washer / dryer, and so much more!

Who watches the common area for trash or handles a broken washer/dryer in the laundry room?

Assuming I did acquire this additional property personally and simply rented it out in the short term, what would be the best way to structure either a future sale or a combined development of both properties I would undertake myself in a few years?
