.: I’m currently renovating a rental property and exploring ways to manage costs without compromising on quality.

You will also need about 6 months of reserves deposited in a traditional financial institution rather than a crypto account.The next step is to find the target property and calculate the acquisition costs and costs of construction along with the after-repair value. 

I would guess an older home might be more cost to insure?

That may increase your cost or limit the coverage you can get.The Year that the following were updated (either partially or fully) would be good to know:- Heating systems- Roof- Plumbing- electricalSome companies will not write properties with systems that have not been updated.As long as you are living there, the proper policy for a 1-4 family is a "Homeowners" policy.

I went to sign up this morning, and it costs an additional $100. 

However, I'm unsure about the costs of maintaining the SL in Spain, especially cause I read in some forums that these costs can be pricey..Do you have any views on the above based on your experience?

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

One thing to take into consideration would be the overhead costs of being a cross-border investor, such as entity setup, property management, higher lending rates and tax filing should you choose to have a CPA.

Looking for something with low acquisition cost, and meets or exceeds the 1% rule.  

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.
