I want guaranteed monthly rents because when I purchase my main focus is cash flow, then equity in the form of added value (renovations, adding extra bedroom, etc).

Both are huge magnets for professionals to rent.With a condo/TH you'll have to factor in HOA fees, but there are some nice options that would generate higher rents.I have a California-based BiggerPockets client who purchased 8 homes in one year in the Southwest Valley.

Purchase price: $726,000 Cash invested: $1,300,000 Sale price: $4,500,000 We are developing a 4 story a luxury Duplex.Property is primed for short term rentals with conservative estimates of ($40,000-$50,000) per month.

Be smart about what package you choose to purchase. 

We currently own one door (split acquisition and closing costs and contribute equally to management and ownership), and have split equity and cash flows from the property - also pretty standard in my experience.My question is this - I want to purchase a house hack and would like to use our current business entity for accounting purposes (tracking income / expenses / etc).

I have used DocuSign for selling and purchasing agreements, but not for closing. 

Consumers make the mistake of thinking that 4% is the interest rate and compare it to other interest rates; it is an upfront fee.Yes, it is very sneaky, but credit card companies are fantastic marketers.Also, the big thing with credit cards is what happens after the 0% period when you need to transfer again, and your credit is much lower than before.

I am looking to cash out refi here soon to pay it off and use again to purchase my next rental property.

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

I am going to try and remote self manage and see how that goes but if it is tough I may use them for my next purchases.
