I am paying mortgage for all the rentals from business accounts.

There are closing cost so either you will need to pay all those or have some downpayment to cover them otherwise the seller is paying to offload it. 

Every owner wants low HOA Dues and then something expensive comes along and they all cry that it's not fair they need to pay an assessment.

So if your house goes from 600k-900k in 5 years you'd have to pay them 180k (20%) on the sale.

As a side note, these are individuals who have already completed a video interview with me and consented to paying for a background check for the position and provided references.

For instance, if you buy a cheap hot tub it will probably pay for itself if you get one or two bookings that you wouldn't have gotten otherwise and it will lead guests to choose your place even if they are not really going to use it

So consider how much asset protection means to you and be willing to potentially pay more because you'll have less lending options available to you, the more complicated you make your entity structure.Hope this helps.

Do what you need to do to buy a property that pays for itself (including reserves, maintenance, etc.), and then hold onto it.

Property Condition: Pay attention to the condition of the property.

What did they pay for the lot?
