That always makes it so much harder to rent, or secure a great tenant.Here's my standard go to list now for long term rental updates:-LVP that looks like wide plank white oak-Ultra Pure white on all the walls-Vertical/ modern stack backsplashes and showers-Pop of color on the cabinets (pop of color can include black too)-Butcher block countertops (lower end) or white quartz countertops (higher end)-Modern light fixtures in brushed brassKeep it neutral still but a couple of style choices with the light fixtures (which are cheap) and it will appeal to the masses.Good luck! 

Remember that books are going to be out of date to the market standard pretty much right after they publish. 

But, for instance, someone who has lost their job, probates, someone who has been transferred, needs an immediate sale, it's been a long time on the MLS but hasn't sold, plus properties not up to MLS standards so they won’t list well on the MLS, and other of "life's occurrences" are all reasons some people sell on subject to.

My business partner and I have a joint LLC (shared business bank accounts / credit cards / etc) - pretty standard stuff.

What about good Standard Operating Procedures (SOPs) to make it easily repeatable?

A third party likely purchased that debt from the original lender (uncollectible by typical debt collector standards) for pennies on the dollar.

But it you really want new financing you  should look into either a standard fannie/freddie investor loan or a DSCR loan depending on your situation

Once the house is done, the loan converts into a standard mortgage.

So if the property is in your name and you write a lease in the name of ABC Management that is completely fine since they are synonymous.What you're referencing is standard operating procedure for anyone starting a sole proprietorship who doesn't want to use their own name exclusively.Hopefully I've explained this well.
