(Of course, there is a factor that higher rating will increase my booking but that is not just coming from adding one or two amenities) Besides item 5 and 6, I am not sure how much other items will attract more guests to my business.

You do have to purchase at least as much real estate as your net sale if you want to defer all tax.TICS are generally cash deals. 

Typically with houses of this age - you'll need structural folks to dig and install piers into the soil.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

Will you need to sell the property?

Etc.Etc.I've found that when you can get crystal clear on what your ideal good deal looks like, it is MUCH EASIER TO FIND IT!

It needed a rehab, and I just couldn't afford it. 

After that all you need is the right team.  

In this case it might be more of a 20/65/15 to get what you need out of selling the 1st. 

U need to flip the return  75% to the money and 25% to you if have any hope of finding someone to do this that is not friends and family.. 10 to 15% is way to little for the risk of being a gap funder.. if the project does not work gap funder is the one who loses money..
