The one caveat I'll point out though, if the value of your first home decreases due to market conditions/changes, recognize that what you owe on the loan may be more then what the property is worth.

Do you know if the co-op will recognize you as the unit owner?

I advise starting with a property manager that has proven results and can help you learn.

That is your proven cash buyer right there.

Credit reports have already been proven to be a poor indicator because the formulas don't correlate with future performance. 

Finding cash buyers is the easiest part of this and can be accomplished by getting a list of all cash closings from your title rep, then locate the entity names that repeat in one year, there is your proven cash buyer.

I do recognize credit score, assets, LTV (the one where I am cashing out $1.75M will be at 70% LTV and is a quad), points/fees, etc. play a role in the rates, but your rate sucks.Also spending $4K to get $17K implies that you are paying 23.5% for your cash out prior to including the interests. 

✨ By investing with other investors through a syndicator, that you have vetted and has a proven track record, investment risk is dispersed among all the investors.

Good read and a great place to start with proven knowledge prior to investing your money. 

I recognize your name from reading the BP forums on San Jose ADUs & Pittsburgh Rentals.
