My point is if we vastly increase rental revenue will the bank significantly increase the loan value it will allocate to us? 

Within my REI business I have spreadsheets for each property to track direct costs and another for  general business expenses like education, office supplies, BP membership, etc that is allocated between the properties at tax time.

I believe following a monthly budget and allocating a percentage of your income to savings, automatically, is a very good way to ensure you are saving consistently. 

I agree with @Mitch Messer, you definitely do not need a Pro membership to start and your capital will be better allocated elsewhere initially.

Going back to the number one, consider allocating a specific amount for commercial syndications.
