However, it's important to note that Section 179 deductions typically apply to tangible personal property used for trade or business, which may not directly align with rental property activities reported on Schedule E.

Typically in many jurisdictions when it comes to this type of niche there are very few who do it and they all work together. 

I typically plan for 5% of my rents to be saved for vacancy.

In the Netherlands, for example, banks typically offer refinancing options with a Loan to Value (LTV) of up to 80% in some cases, depending on the property and the borrower’s financial history.

I've made that mistake in the past and agree that it's not typically a tactful strategy.

Typically, this gets the subs moving at a much faster pace, as who doesn't want that Friday payday check!!!

i agree that a new purchase at 75% equity will typically not have significant cash flow and may even be negative when properly allocating for all expenses.Investing to max equity without reserves is risky and you indicate would result in stress.  

Studies typically cost $3,000–$5,000 but affordable DIY options (around $400–$500) exist for simpler properties.

The sales comparison approach is typically done for residential real estate and will be less appropriate and come in under value because there are no good comps, and even an appraisal using the income approach (unless the appraiser is trained to do more complex commercial appraisals) is probably not going to be the most accurate either because they typically use market cap rates and in this case you don’t have good comparable income properties to find the market cap for the analysis.  

@Austin TessMany lenders have a seasoning period (typically 6-12 months) before you can refinance.
