...can excessive rain really affect my foundation?

For balanced cash flow and appreciation, the basic characteristics we use include:• Single family• Two+ garage• Three+ bedrooms• Two+ baths• Within a minimum and maximum lot size• Built after specific year• Average time to rent below 20 days• One or two levels• Association fees below a specific amountWe eliminate from considerations most properties based on a number of negative characteristics (we have about 50 such "negative" characteristics) including:• Known bad floor plans• Subdivisions with rent restrictions• Known undesirable subdivisions• Properties with traffic or access issues• Properties with excessive drive times• Master bedroom too small• Ratio of lot size to the home's foot print• Tandem garages• Close to nuisancesFor high cash flow properties (usually class B or C) the requirements are quite different and these are usually town homes, condos and occasionally older small single family homes.

@Brett PalmerI would buy more rentals or flips with the excess cash.

Our lease states tenant agrees to allow us to take appropriate corrective action in regards to mold/mildew/moisture conditions.

As stated in the signed lease under section 41 you are not to have excessive possessions outside the unit.

There has been ongoing discussions about adding even more to STRs vs Hotels.Don't they realize that by making business excessively hard, it will just drive people away to friendlier states?

A seasonal vacation rental would absolutely qualify for 1031 Exchange treatment regardless of how much you rent the property (unless you have excessive personal use). 

We do not institute other miscellaneous fees (unless a balance remains unpaid in excess of 30days). 

Yes, you will pay more for an appraisal on multi-family properties but that does seem a little excessive.

To shed light on the subject of insurance commissions, there are two parts to commissions; target premium commission and the commission on the excess.
