Patsy, I had a couple of ideas to ease the strain. You have 32 properties- tenanted with negative cash flow as I see it.
Stage 1)
Starting with the worst lossmaker, offer the properties out to the tenants at full market value informing them of any savings they will make rent versus mortgage. You may want to start this discussion by being brutally honest with them and explaining that you will be increasing the rent or being reposessed yourself. Offer assistance to them. Talk about rent increases to those who could reasonably be increased to nearer market rent levels - I wouldn't suggest going to market levels as some will just bolt. Some will threaten to bolt anyway, few will.
Stage 2)
Can you live in any of these houses? If so sell your own. And aim to move into another you can sell, or rent somewhere.
This will sound totally unpalateable, but you can get back from this position, you can't from bankruptcy
Stage3)
Take control of all outgoings and limit all expenditure to bare bones costs, avoid refurbing - you can't afford it.
Stop thinking of your business in emotive terms and move on - quickly.
Houses wanted in Hull to £80k. All considered- burn outs /refurbs or refurbished. Fast completions no surveys. Commissions paid!
Now taking on cost cutting refurbs/management Croydon and Hull.
