If the bank thinks you are exposed to the market then they will not lend to you period; unless you have a personal net worth to back it up.Many banks have loans limits for any one person or company, so if you are trying to have a large $20 Million portfolio you will probably be dealing with multiple banks.There are lenders who borrow based on the asset, usually, larger loan amounts like $1m or higher, with good terms but with high prepayment penalties.So, to make sure I answered your question.

If you are comfortable with the amount you will need to borrow then put the property under contract.

do you work with the same borrowers or you have new ones frequently?

The (non)lender refused to complete and send a payoff letter, or acknowledge any loan amount or interest rate, when the 'borrower' went to 're'finance.

@Corby Goade If you are planning on doing this a few times a year, I don't think the costs would be worth it if you don't already have a trusted borrower in mind.

A friendly reminder one can only borrow 1 mortgage per FHA loan, and 4 dwellings$815,650

The more money you can borrow on the house and still make money. 

4) Time frame for borrowing money 5) Cash/Collateral to put in (your skin in the game)- Also they'll look for your experience level.  

This business model is one of doing it and keeping everyone happy so the tenant/borrowe never calls the state banking division and rats you out.  

Looking to borrow $75k to $125k depending on terms.
