What are the most important items to compare?

If you're talking about how to reimburse yourself with respect to your investor/partner, if I were that investor/partner, I would expect you to pass one the actual cost of that employee to the project.That said, I would also want to see multiple bids indicating that the cost of that employee was comparable to hiring a third party.

All the while the longterm renters provide good rents compared to the purchase price.

License cost a pittance compared to income potential.

Ensure that you're comparing apples to apples as well, meaning the properties you use for comparison's sake should not only be of a similar style, size, number of bedrooms and bathrooms but should also be in similar quality to the level you intend to remodel your rental.If you are working with an agent and are trying to buy on market, they should be able to help with this.

@Alicia Hall have you compared advantages/disadvantages of being in a community vs getting a tiny house on your own land?

However, my perspective is limited, so I thought it'd be fun to start a conversation comparing the tried and true with the new kid on the block in this changing world. 

Lastly, do not compare a single fam.

Also how does Mashvisor compare?

My current top recommendation comes from a local bank that offers rates that nobody else beats every time I’ve had a buyer compare them with any other firm.
