We decided I’d utilize an FHA loan to buy my first property.

The catch is she is retired and won't have income except SS, thus I would be paying for everything...the HOA, repairs, utilities, insurance, etc.

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

Quote from @Josh Holley: I will also never purchase another property from you again after this interaction and your lack of professionalism.

Not to be a downer, but I'm not clear how I would utilize this metric to manage my properties. 

Use STR-specific insurance to protect both parties and automate operations with platforms like Airbnb, TurnoverBnB, and PriceLabs.Taxable income from the STR must be reported, but you can deduct related expenses like cleaning, utilities, and furnishings.

So you would spend around $25-$30k a month (this was 15 years ago) on police details and require union gate and non union gate if you had non union workforce as well.In DC area, the utility providers are a huge challenge, whether getting permanent power, or water/sewer service etc - good luck.

The income includes things like late fees, a rented garage, and utilities that are billed back to the tenant. 

.)$10K out of my $30K line is only about 34% utilization maximum after I take each chunk.
