That decreases the amount of money I would be approved by a lender to purchase a property.

By approaching from the "objective analysis" rather than "who is the good and bad guy", you are really educating a basic investor.Capital call is a myth/method created by the lender as a temporary measure by the lender to avoid foreclosure.Nonetheless, these capital call is created because the lender itself is willing to take a such very high risk investment that should not happen in the first place.A DSCR loan of 0.85 80% LTV should not happen in the first place.

The additional amount in yr 1 was to help decrease the initial downpayment-Tenant responsible for all maintenance (but I did purchase them a home warranty to use)

One thing that I have gotten from BRRRR is that if you "buy right", you significantly decrease your chance of getting into trouble.

I'm not even sure you can prohibit them displaying a small, temporary political sign at all (legally), though as Theresa said you might be able to prohibit all signs. 

There's absolutely a demand for 4 bedroom homes because many families are moving to Austin and need temporary housing.

I see a temporary seller's market with higher prices along with slightly more inventory.....turning into more of a buyer's market by mid-year up to the election, and then who knows...?

In this time of expectations of rate decreasing I dont recommend buying points.

Those investors who want the LLC but won't pay for it (ie move Title back and forth and get commrecial fiancing) APPEAR to be messing with their corporate veil anyway.Its up to you, but you should do it correctly.Oh, other issues with moving TItle back and forth include invalidating your Title Insurance policy and decreasing the validity of the Chain of Title by using quit claim deeds.The protective benefits of the LLC are commonly touted. 

Great advice above from the GOATs of the MTR forums.I would add that you should also try to get on the lists of corporate housing and temporary housing for insurance companies.
