Cosmo - I personally don't know Phoenix well, but if I had to do this in another city I would look at income levels, crime levels, and population growth (if you can) by zip code and/or area within a DMA as a starting point.

For example of above, there was a person I know, they bought a house for a rental, the square footage was enough to make a 3rd bed out of a dining room, that would increase the month rent by $400.00 a month if they did that..

I also have personal W2 income, if that matters.Is there a loan out there for a set-up like this at 15% down? 

. $50 per bedroom, so a 4-bedroom house will cost you about $150~200consumables - bathroom supplies, kitchen supplies, beverage supplies: $20~30 per week, depending on how much you providewear and tear - towels, linen, kitchen utensils, some furniture: $1000~2000 per yearRepairs/replacement for things that guests break or steal:  $1000~2000 per yearAlso, if your personal use is less than 14 days a year, the entire property's expense is deductible against STR income, but if you use more than 14 days, then you will have to calculate the proportion of how many days it's rented out vs how many days you or your family uses. 

So I wonder if I can sell my home in Idaho, purchase the new one under my personal name, then how many months or years must pass before I can setup an LLC as the owner of my primary residence, or if you think that will be a good idea? 

Second- these developments where the same person develops, builds, and then requires you to use them for management- they always suck.

Was that person me or another person as that sounds like something I have been telling people? 

That is just what I am seeing personally, and I work with investors all over the country. 

Quote from @Jaycee Greene: Hey Jaycee, we currently lend on several loan types: Fix & Flip up to 90% LTP, BRRRR, New Construction, Bridge Loans, & Multi-Family.For myself personally, I'm looking in the Orlando, Philadelphia, and Southern NJ markets, 1-4 units.

I inherited a partnership in a 22 unit commercial building with 8 restaurants, a grocery store, a couple of personal care services, and various other businesses.
