And, there is every possibility that I am able to assume quality debt if I am a low-leverage purchaser.

You haven't given many details so it's difficult to give you a quality answer for your situation.

@Joy McQuearyRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

The best way to estimate expenses is experience and knowledge of your specific asset type and market.For vacancy, that will depend on your market and the quality/desirability of your type of unit.

But with 40 ft lots, that same space could accommodate 179 homes.By increasing density in this way, we can deliver homes that are more affordable, while still meeting the needs of families who want single-family homes with their own yards.Higher density doesn't have to come at the cost of quality or livability.Much respect and love what you're doing at BP.

Appliances supplied mean better rents and a higher quality tenant.The location of the rental and the type of tenant you want will dictate what you supply.Finding a good supplier of new appliances will get your cost down to the point that used doesn't make sense.

If you ask nicely and promise not to share, you can usually get good financial information on the properties that are currently operating as a STR.If you're just starting out looking, you may not be aware of just how many cabins out there are poor quality builds due to the lack of codes.

@Marc ShinLike @Andrew Steffens said, for big items, go with quality.

Also make sure you have quality insurance with an umbrella policy.
