Just be prepared and build contingency into your timeline and budget.A couple of notes on the specific question: Construction loans are riskier for banks (no finished home as collateral) so hard to find info.  

Just put realese clauses and substitution of collateral in the agreement.

A commercial loan with cross collateralization of the properties on a 5 year note with a 15 year amortization schedule.

I currently have the property as collateral in the event of default.

@Richard Miller Even if you loan the money and require a 30% return on your money, you won’t be able to use the property as collateral since the bank will require it for the FHA loan.

I’d like to start purchasing a few more, but would also want to hold those in an entity (LLC) to shield against personal liability for events on the property - the LLC does nothing to shield against the debt, for which other collateral or personal guaranties are always going to be required and I am fine with that.  

Debt to income ratio is also used to understand whether the income would be sufficient to justify the added debt.Collateral: the higher the value of the collateral used by the borrower as security the lower the perceived risk may be.Legal Compliance: lenders need to ensure the investment and loan are in compliance with all legal requirements and regulations.What about the loan-to-value (LTV) ratio?

This means they are in the driver seat in regard to collateral and means even more risk in regard to a revolving line of credit.

I'm also assuming that I can get into this property and by the end of the year use the property as collateral to access another loan to purchase my next multi-unit and do a few wholesales in between.

When we spot the house we have 20% down (or cross collateralize) and the banker ok's the buy on the phone so we an make a non contingency offer.
