Make sure you are cash-flowing after taking into account all the expenses and saving for future repairs. 

This is because you need to account for emergencies and other unexpected costs that could eat into the budget.

There will be some monthly expenses like supplies not accounted for but at the same time I didn’t account for the cleaning fee we will be earning.I do plan on using dynamic pricing, airbnb, and vrbo.  

Ask the guys trying to sell solar panels (which by all accounts is an accretive investment for just about anyone) about the challenges they have - you'll have the same ones, except at a 10x price point.The other main challenge is build quality. 

Credit, LTV and DTI will always play the largest roll.

They do collect a lot of personal info like full access to your accounts to make decisions etc.

In search of accounting software specific to real estate for tracking expenses of rental properties (including LTRs in LLC with property manager and self-managed STRs).

@Jack Seiden There is no fiduciary relationship established because the licensee is not acting as anybody's agent when they are buying and selling on their own account. 

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?
