There are plenty out there with fair rates and lower fees.

I can finance regularly with non recourse and have a note of about 75k less the down but plenty of funds just sitting there in the solo doing nothing.

I am sure he has come across this plenty of times.

Another downside is you loose on the advantages, of the Federal Tax Code, by not closing in the name of a LLC (you can elect to have a LLC taxed, as a S Corporation which is a whole other conversation).If you want to close in the name of a LLC, Mortgage Lenders will offer you Commercial Loan Terms (25-30% down, a 15-25 year amortization, and a ballon due in 5-7 years).

If you don’t have a large down payment saved up, don’t worry—there are plenty of options available . . .”A trusted lender will go over the various loan types with you, any down payment requirements on those, and down payment assistance programs you may qualify for.

., with the rapid rise of STRs, you will find that many insurers offer STR policies.We use Proper but it is very expensive but very comprehensive.

This would likely take coordination with a tenant at some point - (ie - plenty of notice to them that they must vacate in order for you to sell the property)Since your current home is free and clear -  you could do a cash out refi or take out a new mortgage on the new house to be able to buy your paren't house and pay off the mortgage.  

I still have plenty time left saving but when the time comes I’ll either be looking into conventional  loans, or some type of remodel loan to pay for the repairs of the property I am looking to fix up, because as far as I’ve seen so far it’s hard to find a good deal starting out unless you buy it as discounted as possible and put some sweat equity into it, let me know your thoughts on that ur possible.

While the market can go up or down in either investment, Real Estate is the only one of the two that offers income opportunities through rental income, that stocks don't, and can often help ride out the storm of market fluxes.Also, the Greater Phoenix market (that includes Scottsdale) historically nets 65K+ Californians per year. 

As a retired CPA, I saw plenty of tax returns by these firms that clearly were done poorly.
