Make it your business practice to post the notice to pay or quit precisely on the day after the grace period ends, every time.

Partnership guaranteed payments can be either for capital or services. 

4) Keep my money in a guaranteed savings account making 4.5%, until rates drop more or something changes, and the numbers are better to make a move?

They tested the appliances thoroughly and offered a one-year guarantee.

I was considering taking out a $240K HELOC with a 10-year draw period and pulling $160K from it to build the next rental property.

Quote from @Shayan Sameer: Quote from @Zachary Deal: As several folks have mentioned leveraging equity in current property you owned is a great tool but still comes with the some of risks as you had before using hard money debt as there is never a guarantee your new project will be a success (there will always be risks with real estate investing).Leveraging your investment property would probably be the first step I would take. 

I am trying to calculate my returns over a 10-year period using the rent-by-room strategy, which results in significantly more cash flow than traditional rentals.

@Connor O'Brien CHA does release payment standards that can be found on their website but those are maximums, not guaranteed. 

Id keep looking if it was not an approved short sale ( even an approved short sale takes a very very long time and theres no guarantee that you will even close on the house after months of waiting). q1)There are plenty of non traditional lenders that could offer you construction financing if the numbers make sense but it will cost you with points and a higher rate.

I predict that the guys who are fully leveraged and cash flowing $100 per month will be motivated sellers when the next big correction happens.actually its either them or they walk and its their lenders selling that is what happened in that time period.. and was pronounced in certain markets.for me personally  I don't want to risk  my credit and finances and borrow 75k to make 1200 a year... or even 2400 a year if its a market that has a history of no appreciation and I don't feel there is going to be any significant appreciation.. 2 to 3% a year does not cut it.but I will take 500 a month negative or 10k a month negative if I think there are huge gains at the other end..
