With Apartments.com I can automate rent payments, have the security deposit paid, and have tenants upload their proof of renter’s insurance.

Hi Adam,Your lender should definitely know the down payment amount much prior to closing.

Does the heloc still account for the down payment?

If lower then you'll need 10% down payment.

However, as long as payment continue to be made, I don’t see their incentive to call it on full

Cap Rate is 0.43%, and Cash-on-Cash Return is calculated by dividing annual cash flow by total cash invested.The property's annual cash flow is $1,268, calculated as $1,268 - $2,932 based on a 20% down payment and a 6.5% interest rate over 30 years.

I make a little over 100k a year and have 50k currently ready for a down payment. any insight would be helpful. 

Add the principle for the next payment and you save that payment.

Purchase price: $370,000 Cash invested: $2,500 I'm thrilled to share that I recently purchased a multi-family property with a down payment of just $2,500, thanks to an FHA loan, alongside a generous $17,500 grant from Rhode Island.

It works like this: pick one of their turnkey-ish houses from their list, or bring your own, get financed for a 50k house with 10k down, pay interest only @ 10% for two(or3) years with 5% accrued interest tacked on to the balloon payment after 5 years with possible 2 year extension.
