Help with Spanish Taxes

Can anybody who is well informed and successful in the Mijas Costa Area with sucessfully paying their taxes with no problems please advise where I can find a trustworthy accountant to help with paying tax on our long term let.  I would like to know what we can claim back on a mortgage payment of 1,100, interest 600 euros and income of 650 euros.  I have used numerous tax advisors and not one of them gives me a breakdown and all charge a significant amount of money. I need advise and help - does anyone know of anybody on this site? willing to pay of course. So far I am left struggling with submitting everything I can think of - bills etc cleaning but I have been told I cannot claim the cleaning costs because the lady works for herself and is not VAT registered. Nor can I calim for cleaning products unless the supermarket rubber stamps the receipt and issues a seperate Factura . All sounds nonsense to me. 

Although not well informed and successful in the Mijas Costa Area with sucessfully paying their taxes with no problems, I use http://www.advoco.es/ for paying my non resident taxes.  If you check their website you may find the information you are looking for. They are very professional and the charges I pay are very reasonable. Hope this helps.

anyone know what a FORM 036 is pls?

Those persons or organisations that are non-resident in Spain or not established within the applicable territory of the VAT shall file Form 036 at the Tax Agency local office or branch corresponding to the tax address of their representative or, if not appointed, that of their place of operation.

Can anybody help with advice on Inheritance Tax in the Manilva area please.  We have two sons one is included on our legal documents the other one did not want to be included.  If one of us dies do any of us pay inheritance tax, we believe you do not pay inheritance tax on any property value under 350,000 euros?  We do not live in Spain.  Will things change when we enter Brexit?

I believe you do pay IT regardless of the property value.
